Contract.

Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed

Cardiac muscle have a greater need for oxygen than skeletal muscles because they use up more energy in a shorter amount of time so they require regular refills of oxygen.

I believe you are talking about the hyoid bone. It's the only bone in the body not directly connected to another bone. It is instead attached to ligaments and muscles.

It is an example of both, as biology and physics overlap because the boundary of science between them is not always so clear.

Muscles contain certain proteins called contractile proteins which enable it to contract and relax to bring about movements.

I believe you mean striated

Muscle cells are smaller than muscle tissues.

Type I muscles

it is located underneath the sebacecus gland :)

Working in antagonistic pairs allows the body part to move back to its original position. For instance, your fingers wouldn't work very well if you only had a muscle to flex them, but not extend them.

Rectus femoris, vastus lateralis, vastus medialis and sartorius.

Accumulation of lactic acid in the muscle from anaerobic ATP production.

Yes, it will just take longer to be absorbed (the maximum effect is around 30 minutes instead of 2-3 minutes after injection). You will still probably feel effects within 5 minutes (faster than snorting).

Biceps are the top part of your upperarm, your Triceps are the bottom part of your upperarm, and your deltoids are the muscles on your arm next to your shoulders.

The origin is the immovable end, while insertion is the movable end.
Some muscles have more than one origin, like the biceps brachii. The insertion of the biceps brachii is attached to the radius of your forearm while the origins are located on your scapula.

Muscular Hypertrophy is the increase in muscle size due to increased number of myofibrils et al.

Each muscle fiber (myocyte syncytium) consists of a cell membrane (sarcolemma) containing myofilaments actin and myosin arranged in end to end segments called sarcomeres. Muscle fibers are produced by fusion of multiple myoblasts during development, with the end result being a multinucleated syncytial cell which begins to produce myofilaments.

Muscle growth occurs by production of additional myofilaments within each muscle fiber, the process called cellular hypertrophy. This results in enlargement of the whole muscle, also called hypertrophy. The number of myocytes remains the same.

Existing myocytes can be repaired during regeneration following a severe injury. Satellite cells immediately adjacent to each muscle fiber proliferate and grow, fusing to eachother and existing damaged myofibers. Severe damage also results in fibrosis, or replacement of myofibers with stiff connective tissue, and results in impaired movement. In any case the number of muscle fibers remains the same.

area in the muscle between the two Z discs.

The general name for the group is hamstring. The technical names of the two primary muscles are semitendinosus and semimembranosus.

The primary movement of each muscle is to contract and relax. Depending on how it is anchored to the bone will dictates the direction it moves.
