Muscular System

epimysium

its called musclepian

Physical Activity

There are plenty of them that are used to produce the action of walking, but mainly the muscles of the lower extremities do most of the work. These include the quadriceps, hamstrings, adductors, gastrocnemius, and soleus. The joints used are the iliofemoral (hip) joint, the tibiofemoral (knee) joint, and the talocrural (ankle) joint.

Arrector pili is the muscle the raises hair. This is taught in health class.

Probably the Biceps Brachii (commonly called Biceps).

Flex the elbow (humeroulnar joint)

You will know when a girl has an orgasm when you can feel her vaginal muscles contract a little and her legs and thighs will tighten, also her vagina will start getting wetter and she will start to sweat and her breathing will become increasingly rapid along with her heart rate.

A wave of pleasure with intense muscle contractions "down there" in particular and usually you'll get very wet too. If you're not sure then keep going until you are! There is no harm in it.

If you're a guy, you'll know you have if your hand is covered in sticky stuff.

deltoid

The muscles that require conscious control are called voluntary muscles, or skeletal muscles.

extensor digitorum longus, the extensor hallucus longus and the peroneus tertius muscles help dorsi flexion
tibialis anterior

All from Mesoderm, except the eye muscles that originate from ectoderm

This question sucks

Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon. When the impulse travels down the axon to the muscle, a chemical is released at its ending. Muscles are made of long fibers connected to each other longways by a ratchet mechanism, the kind of mechanism that allows the two parts of an extension ladder to slide past each other and then lock in a certain position. When the chemical impulse from the motor neuron hits the muscle, it causes to muscle fibers to rachet past each other, overlapping each other more, so that the muscle gets shorter and fatter. When the impulses from the nerves stop, the muscle fibers slide back to their original positions. Each motor neuron connects to just one muscle, say the bicep on the front of your upper arm that lifts your forearm, or to the triceps, the one on the back that extends your forearm. But when you move, you never think, "I'd like to contract my bicep two inches and relax my tricep two inches" -- instead you think, "I'd like to put this cake in my mouth!" How does the brain translate from the general idea to lift something to your mouth to specific commands to muscles? It does it in stages. In the cerebral cortex, the commands in the neurons there represent coordinated movements - like pick up the cake, hit the ball, salute. The cortex then connects to a sort of console in the spinal cord that overlays the motor neurons. This console lays out arm position in space, up-down, left-right. Each desired arm position then is read out as a collection of specific commands to each motor neuron and muscle.

because during slave trade they breeded the strongest blacks together to have offspring that work just aswell so in its in there genitics

The 3 different types of muscle are smooth, cardiac, and skeletal muscle. Smooth muscle is located on the walls of hollow organs, cardiac muscle is located on the wall of the heart, and skeletal muscle is located on skeletal muscle organs (most organs). Their functions include movement in walls of hollow organs, pumping of blood, and movement of bones, heat production and posture, respectively. Cardiac and smooth muscle are involuntary, whereas skeletal muscle is voluntary. Both cardiac and skeletal muscles have striations, but smooth muscle does not.

Ice it A LOT and then take a hot bath... sleep with a heated cushion or something related, take advil the next morning and repeat. Shouldn't last more than 3 days or so... happens to my muscles all the time

and when you bathe you can use epsom salts too and try to stretch the muscle just a little bit and just take pain reliever too it really helps numb your body for a couple of hours so it doesn't hurt as much.

antagonist muscle

The deltoid sits on top of the glenohumeral joint and helps to abduct and also to rotate the humerus.

Flat bones, like scapula

All I know is that acetylcholine is the only neurotransmitter that transmits signals from nerves to skeletal muscles, so anything that blocks it would probably have the effect of you wanting to move your muscles, but either not being able to, or moving weakly.

Just a (educated) guess.

It would cause spastic paralysis (muscles are contracted and unable to relax)

The heart contracts independently ad spontaneously. Otherwise, you would have to consciously think about making it beat, and would probably die.
