What is muscular stamina?

Muscular stamina is the muscles up your butt and if you do a $h!t regularly then you will build up your muscular stamina quite quicky actually, and also if you smell a dogs a$$ that will also help, hope I helped.

What is muscular force in simple words?

Muscular force is the force applied using parts of the body like arms or legs. It is force that results due to the action of muscles, and is a contact force, since there is a contact between the surfaces. Muscular force is needed whenever movement of the body occurs. Walking, lifting, getting up from a chair, crossing a leg, etc. all require muscular force.

What muscle cells consisting of a single nucleus are believed to be important for muscle hypertrophy?

Skeletal muscle cells containing a single nucleus, called satellite cells, are believed to play a crucial role in muscle hypertrophy. These cells are involved in muscle repair and growth by contributing new nuclei to muscle fibers, aiding in protein synthesis, and increasing muscle mass in response to resistance training.

What is the importance of acetylcholinesterase in muscle cell contraction?

If the action of acetylcholinesterase wereinhibited, the level of acetylcholine would increase as well as the duration of its action. The effect would cause muscle spasms.

This is because an electrical signal, or nerve impulse, is conducted byacetylcholine across the junction between the nerve and the muscle (the synapse) stimulating the muscle to move. Normally, after the appropriate response is accomplished, acetylcholinesterase is released which breaks down the acetylcholine terminating the stimulation of the muscle. The enzyme acetylcholine accomplishes this by chemically breaking the compound into other compounds and removing them from the nerve junction.

If acetylcholinesterase is unable to breakdown or remove acetylcholine, the muscle can continue to move uncontrollably.

Electrical impulses can fire away continuously unless the number of messages being sent through the synapse is limited by the action of acetylcholinesterase.

Repeated and unchecked firing of electrical signals can cause uncontrolled, rapid twitching of some muscles, paralyzed breathing, convulsions, and in extreme cases, death.

Some cells such as human nerve and muscle contain many more mitochondria than do other?

Their function is basically to provide energy to the rest of the cell through respiration (break-up of food substrates into simpler usable products). So quite obviously, as the nerves and muscles use up the most energy, they have the most mitochondria.

Is smooth tissue a muscle tissue?

Smooth tissue refers to a type of tissue that lacks striation and is typically found in organs like blood vessels and the digestive tract. Muscle tissue encompasses three types: skeletal muscle, cardiac muscle, and smooth muscle. Smooth tissue is a specific type of muscle tissue known as smooth muscle tissue.

What is the advantage of having many nuclei in a skeletal muscle fiber?

Having many nuclei in a skeletal muscle fiber allows for efficient repair and regeneration of the muscle tissue. It enables the muscle fiber to synthesize proteins and grow in response to exercise or injury. Additionally, the multiple nuclei provide more genetic material for protein production, enhancing the muscle's ability to adapt and increase in size.

Is the soleus muscle superficial to the gastrocnemius?

The answer would be false. The soleus muscle is superficial to the tibia NOT the gastrocnemius.

How do you remove a Pella patio sliding screen door it appears to have a double roller system at the top and does not tilt or otherwise come out of that track system does the track system split?

It depends on what kind of door it is, but Pella's 'support center' should have the manual. I found mine at: http://web.pella.com/supportcenter/Documents/WoodOwnersManual08_3.pdf Hope that helps. * * * Do you see two screws on the top where the wheel(s) are attached? I discovered that I could just unscrew them and pull the door completely off the track. The "wheel" is actually a horizontal strip that glides in the track. Should be easy to pop the door back in and screw in place when I'm done staining it.

What is the function of motor end plate?

A motor endplate is a large special synaptic contact between motor axons and each skeletal muscle fiber. Each muscle fiber forms one endplate. Its function is to transmit impulses from nerves to muscles.

Does the motor neuron send a signal to or from the muscle fiber?

Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.

The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.

Compare and contrast in terms of structure and function the three different types of muscles found in the human body?

Well you only have 3 types of muscles in the human body. Cardiac, Skeletal and Smooth 1 Cardiac Muscle... with is only found in the heart. The specialized striated muscle tissue of the heart, the myocardium. Cardiac muscle is in some ways similar to skeletal and smooth muscle . For example, all three contract when a rise in calicum inside the muscle cell allows interaction between actin and myocin filaments. However, cardiac muscle has a unique structure, and differs in the way that contraction is initiated and regulated. 2.Skeletal Muscle... usually voluntary muscle made up of elongated, multinucleated, transversely striated muscle fibers, having principally bony attachments. Also called striated muscle. Skelekal muscles moves the skeleton and is responsible for all our voluntary movements, as well as for the automatic movements required, for example, to stand, to hold up our head, and to breathe. 2. Smooth Muscles... Muscle tissue that contracts without conscious control, having the form of thin layers or sheets made up of spindle-shaped, unstriated cells with single nuclei and found in the walls of the internal organs, such as the stomach, intestine, bladder, and blood vessels, EXCLUDING out side the heart. The cardiovascular, gastrointestinal, genitourinary, and respiratory systems are composed mostly of hollow organs (tubular or sacular), which transport and/or store fluids (either liquids or gases) within the body. The walls of these organs contain smooth muscle, a type of tissue which enables them to constrict or dilate, in this way retarding or facilitating fluid movement as required. This is accomplished by the shortening or lengthening of the individual smooth muscle cells, which occurs in a co-ordinated fashion because the cells are electrically coupled by intercellular connections, known as gap junctions. Other structures in the body that contain smooth muscle include the myometrium - the muscular wall of the uterus - which is responsible for the rhythmic contractions of Labor, the piloerector muscles, which cause skin hair to stand up; and the irises, which control the diameter of the pupils.

Why does the muscular system need the circulatory system?

the cardiovascular system needs the skeletal system because the skeletal system protects the organs of the cardiovascular system with the ribs and other bone parts. Also bone produces erythrocytes (red blood cells) and leukocytes (white blood cells) which of course are essential for the cardiovascular system

How many skeletal muscles are in your body?

Approximately 640. Different experts claim approximately 639 to 650. There are about 640 Skeletal Muscles.

Why would drinking milk help the muscular system?

Milk is a rich source of protein, which is essential for muscle growth and repair. It also contains calcium and other nutrients that support overall muscle function. Drinking milk after a workout can help replenish glycogen stores and promote muscle recovery.

Are cardiac muscles attached to the bones?

No. Cardiac muscles are attached to the pericardium - a layer of tissue that surrounds the heart and the Great Vessels. The sac rests on the diaphragm and is connected by various bits of connective tissue to the thoracic cavity.

What is a solution for muscular weakness?

A solution for muscular weakness can include regular strength training exercises to build muscle mass and improve strength, proper nutrition to support muscle health, adequate rest and recovery time for muscles to repair and grow, and consulting with a healthcare professional for personalized advice or treatment options.

Is 1.15 creatine level high for a young muscular adult male?

A creatinine level of 1.15 mg/dL is within the normal range for a healthy adult male. However, the interpretation may vary depending on the lab's reference range and the individual's muscle mass. It's best to consult a healthcare provider for a comprehensive assessment.

All or none principle?

The all-or-none principle established by the American physiologist, Henry Pickering Bowditch states that the strength of a nerve's response to stimulus is completely independent from the strength of the latter. The nerve will still give a complete response even if the stimulus exceeds the threshold potential of the nerve.

In the reflex arc a muscle or gland is considered to be the?

In the reflex arc, a muscle or gland is considered to be the effector. Its role is to respond to the stimulus provided by the sensory neuron and produce the appropriate action, such as muscle contraction or gland secretion.

Can you live without a tendon?

Yes, you can live without a tendon as long as other muscles and tendons can compensate for the lost function. However, losing a crucial tendon can significantly impact mobility and functionality in the affected area.

What is the plasma membrane of the muscle fiber?

The plasma membrane of a muscle fiber is called the sarcolemma. It surrounds the muscle cell and is responsible for controlling the passage of substances in and out of the cell, as well as transmitting signals for muscle contraction. The sarcolemma is essential for maintaining the integrity and function of the muscle fiber.

What is the animal muscular system?

Like humans, animals also have to have the use of muscles to help provide movement and to some degree, protection.

Its important for almost every living creature to have a muscle system. The muscles work in antagonistic pairs to provide different movements such as flexing and extending two different muscles play the different roles and while one is working the other is relaxing.

How are muscle cells adapted to release a lot of energy?

It has large amounts of mitochondria, which are used to release energy.

What are the Skeletal muscle cells that function in calcium storage?

Sarcoplasmic reticulum is the type of skeletal muscle cell that functions in calcium storage. It plays a critical role in regulating intracellular calcium levels during muscle contraction and relaxation.
