The muscular system allows humans to move. Muscles also provide strength, balance and heat.

What biceps and triceps called?
The biceps and triceps are muscles. They flex and extend the forearm, respectively, so they are considered antagonists.
What happens to muscle during exercise?
During exercise, the muscles get stronger and the bone mass gets larger.
What are the functions of the connective tissue wrappings of the skeletal muscle?
endoneuuronium isolates form other neuronal procisses
*Endoneurium - insulates each nerve fiber from the neuron processes adjacent to it.
Perineurium - forms fascicles.
Epineurium - forms cord-like nerve.
What is the prime mover muscle of shoulder horizontal adduction?
Because shoulder horizontal adduction is performed when the arm is horizontal position (i.e., the elbow is level with shoulder) and adduction is movement toward the center of the body, shoulder horizontal adduction is performed primarily by
pectoralis major and anterior deltoid, with an assist by latissimus dorsi.
Which muscles are used when inspiration is forced?
the sternoclediomastoid, scalenes and external intercostals all work to increase throracic volume. hope that helps
Does decreased ATP occur within a muscle cell during oxygen debt?
Oxygen debt is the deficit of oxygen resuting from intense exercise. During exercise, the body cannot generate enough ATP (energy) to meet the needs of the muscle. This produces lactic acid, which causes muscles to fatigue. Oxygen is required to metabolize the lactic acid and replenish energy stores. How do we do this? We breath, rapidly to bring in large amounts of oxygen. Think of this concept as a checkbook with money being oxygen and writing checks as exercise. If you write checks, but run out of money, your account will go into debt. How do you get out of debt? You get more money.

Smooth muscles are involuntary meaning that you cannot control them. They are found around organs in the body such as arteries, stomach, and intestines. Smooth muscles are .5mm long and are spindle shaped. Smooth Muscles also contain nerve endings.
What is the part of the brain that coordinates your muscles so you can walk?
The cerebellum (infratentorial or back of brain) is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.
Five golden rules of gross skeletal muscle activity?
1. All muscles cross at least one joint.
2. Typically, the bulk of muscle lies proximal to the joint crossed.
3. During contraction, the muscle insertion moves toward the origin.
4. All muscles have at least two attachments (origin and insertion).
5. Muscles always pull, they never push.
How do the circulatory muscular and skeletal systems work together?
The muscles move bones and bones provide blood cells to the circulatory system. When muscles contract, they help move blood in the veins back to the heart. Many parts of the body work together like this.
What muscles are found in your belly?
If your fat and on the sides you have wiggly and giggly stomach on the side it's called LOVEHANDLES..Your Welcome
What are cardiac muscle fuel sources?
The heart muscle uses a fuel mixture of: fatty acid, ketone bodies and glucose
- fatty acids are the preferred fuel of the heart.
- glucose is the least favored fuel.
-ketone bodies and lactate are used under stress (high demand of energy).
-small limited stored phosphocreatin as a reserve energy.
It tells you the number of origins. "When biceps, triceps, or quadriceps forms part of a muscle's name, you can assume that the muscle has two, three, or four origins, respectively. For example, the biceps brachii muscle of the arm has two origins, or heads."
- Human Anatomy & Physiology. Eighth Edition. Elaine N. Marieb page 321
How many types of muscles are there in your body what are they called?
Yes, there are three main kinds: smooth, which is controlled by the autonomic nervous system and we don't have voluntary control over, skeletal, the muscles that we control and move us around, and cardiac, the muscle that is found in the heart.
What is the total number of muscles in the body?
There are 639- 640 muscles in the human body. There are about 30 muscles in the face alone.
Do Epimysium surround an entire muscle?
No, only endomysium. Likewise for Cardiac muscle. Skeletal muscle is the only one with epimysium (which is continuous with fascia) perimysium and endomysium.
Is your brain strong to answer this mind test?
Brains are not strong or weak. Muscles can be described in that fashion. The brain is a lump of neutrons and similar nervous tissue, not a muscle.
Which extrinsic eye muscle turns the eye laterally?
The inferior oblique muscle, which is located in the anterior portion beneath the eye (hence the inferior in the name). Its full Latin name is obliquus oculi inferior.
Is the aponeurosis a ropelike piece of muscle that forms indirect connections to muscle of the leg?
An aponeurosis is not rope-like, as a tendon is, but is a broad sheet of connective tissue that connects muscle to other muscle or to bone.
What muscle is the flat bone attached to?
there are several flat bones... The Scapula (shoulder blade), Sternum (breast bone), Cranium (skull), Pelvis and Ribs are all considered to be flat bones.
What are three things muscles can do?
Allows for organism movement (skeletal muscles) or organ movement (cardiac muscles, smooth muscles of the gastrointestinal tract) Generates heat (in endotherms) Allows for blood to return to the heart after it has flowed to the extremities (by squeezing the veins when they contract)
