The muscles in the leg are considered long muscles. As the muscles in the leg contract and relax they work to provide movement. What would happen if the upper leg muscles were damaged?

if the upper leg muscles were damaged, (You would not be able to extend the leg straight).

Explanation:

The upper leg muscles, which can also be called the thigh, are made up of three sets of muscles which include:

--> the hamstring muscles: These are located at the BACK of the thigh. They are made up of three long muscles which includes the semimembranous muscle, the semitendinosus muscle, and the biceps femoris muscle.

--> the quadriceps muscles: They are located at the FRONT of the thigh. They consists of four individual muscles which includes the three vastus muscles and the rectus femoris.

--> the adductor muscles: They are located at the medial compartment of the thigh and is consist of the following muscles: gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus.

The quadriceps, hamstrings and adductor muscles work together to straighten (extend) and bend (flex) the leg. Therefore when there is damage to the upper leg muscles, you would not be able to extend the leg straight.

explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
