Using the Butterfly stroke in swimming as an example (see video); What is the significance of having a muscle originate at the Illium and insert at the Humerus?

Most of the muscles of the skeleton are attached to areas very close to the joints, so their arms, although they are very small, their mechanisms allow the movement of the human body. (a) How are they considered from the point of view of force efficiency? (b) What are the biomechanical benefits?

With the paired muscles along the spine, a more origin (attachment) will allow the muscle to generate more rotation and/or lateral flexion when only one side of the paired muscle is activate.

Identify a muscle that everts the foot and two muscles of either the hand or foot that are considered to be intrinsic muscles of that structure. Be sure to state clearly which muscle everts and which muscles are intrinsic.

Name one muscle that has its origin from the process pointed with the arrow.

Name the types of muscles and mention to characteristics of each.

Locate and list two different pairs of muscles that act as on the body as agonist/antagonist. (That is, in each pair, one muscle will produce a movement, such as flexion, that the other muscle will undo, and produce extension; abduction/adduction, etc. are other ways that muscle produce opposite actions on the same part of the body).Name two muscles that act as “fixators.” (What are fixators?) What joint or joints are they helping to stabilize?Why is the biceps brachii called a “bicep,” while the triceps brachii is called a “triceps?”What is the difference between a muscle with “longus” as part of its name and a muscle with “brevis” as a part of its name?

Discuss the different ways of naming muscles, and give two examples each

Select the two most appropriate muscle(s) that perform(s) this body movement: Temporalis Zygomaticus Masseter Sternohyoid Occipitalis Buccinator

Discuss the functions of the different types of levers found in our body. How do these different types of levers make our body more useful. Explain each type of lever, the position of the fulcrum, load, and applied force and give an example of each.
