Where can you find the involuntary muscle?
Involuntary muscle is muscle that contracts on its own. You do not have to think about contracting it. You find this type of muscle in hollow organs such as the digestive tract. You also find a type of involuntary muscle in the heart.
How is a prosthetic limb mimic the human muscular and skeletal systems?
A prosthetic limb mimics the human muscular and skeletal systems by using advanced materials and engineering to replicate the function and movement of natural limbs. It often incorporates joints and components that allow for articulation similar to human joints, while actuators or motors can simulate muscle movement. Additionally, prosthetics may be designed with a lightweight structure to balance durability and mobility, closely resembling the biomechanics of a natural limb. Some prosthetics even integrate sensors and AI technology to enhance user control and adaptability.
What body parts are in the muscular system?
It is usually the tissues and the tendons and the muscles of course
What is the advantage of having multiple nuclei in one skeletal muscle cell?
the ability to produce large amounts of the enzymes and structural proteins needed for contraction
What muscle flexes and abducts hand at the wrist?
There are several muscles involved in flexing the hand.
- Palmaris longus (flexes hand)
- Flexor carpi radialis (flexes and abducts hand)
- Flexor carpi ulnaris (flexes and adducts hand)
- Flexor digitorum superficialis (flexes proximal and middle phalanges, flexes hand)
- Flexor digitorum profundus (flexes phalanges and hand)
- Flexor pollicis longus (flexes thumb and hand)
- Flexor pollicis brevis (flexes thumb)
There are also a few more I did not include that flex specific digits of the hand
What heavy exercise the buildup of lactic acid in muscle cells results?
Oxygen Debt- A cumulative deficit of oxygen resulting from intense exercise; the deficit must be made up when the body returns to rest.
Rhomboids
What Cardiac Muscle makes up what organ?
Cardiac muscle is made of cardiac muscle cells. Cardiac muscle is under the control of the autonomous nervous system and is not susceptible to fatigue
Where is the masseter muscle located?
The masseter muscle is the major jaw muscle, and is able to generate more force than any other muscle in the body.
The muscle that forms the anterior wall of the abdomen is called the rectus abdominus.
What muscles make up walls of most internal organs?
Much of our internal organs is made up of smooth muscles. Smooth muscles make up the walls of many organs; eg bladder, gallbladder, arteries, and veins, digestive tract and oesophagus. The smooth muscles are controlled by hormones and the nervous system. Smooth muscles are often called involuntary muscles because we cannot control there movement.
What is shrinking of muscles do to lack of use called?
Muscles shrinking when not used is the body being economic.
Muscles are made up of cells, and cells are living things. Living things need energy - food, one way or another, only to remain alive.
So even if you aren't using them at the moment, it's costing the body an effort only to keep them around.
And the body is economic. It doesn't like to spend effort on something that isn't being used.
If you're not using a muscle(much), the body will eventually stop maintaining those muscle cells it doesn't need. And the muscle as a whole will begin to shrink. It'll shrink to the point where what remains is what it needs to be able to do what you normally ask it to do.
Why is it important that the uterus is made of muscle and elastic tissue?
How do your butt muscles work?
There are little men inside the "anus" (canal that poo comes out off) that squash your food into neat, little, brown packages. They then THROW the neat, little, brown packages into the toilet.
This answer is scientificaly proven.
Where are sensory stretch receptors of the withdrawal reflex located?
they are located in the limbs, because the limbs are the effectors of the withdrawal reflex.
What are the synergistic muscles of the thigh?
Biceps and brachioradialis. The bicep is the prime mover in elbow joint movement and the brachioradialis acts as a synergistic muscle to stabilize the joint, thus aiding in the motion.
Which muscle controls the contractions of the heart?
Officially the sino-atrial (SA) node sets the rhythmic pace of the heart. The impulse from the SA node that signals the atria to contract is slightly slowed down at the AV node. The effect of this delay is that the ventricles receive the impulse to contract a split second later and so the heart can function as its supposed to. Without that split second delay all four chambers would be contracting nearly simultaneously, and the heart would not be able to function efficiently.
Also included are the AV bundle, and Purkinje fibers. These are made up of modified cardiac muscle.
AV bundle originates in AV node, extends by two branches down the two sides of the interventricular septum, and continues as Purkinje fibers. Purkinje fibers extend out to papillary muscles and lateral walls of ventricles. The nerve supply consists of sympathetic nerves-accelerator nerves and
Vagus fibers-inhibitory, or depressor, nerves.
Where is the Latissimus dorsal located?
The location of the latissimus dorsi has been mistaken by a vast majority of people. The latissimus dorsi is located in the back on a person's left side.
