Chapter 7, Problem 2IP
Summary Introduction
To construct: Chart listing all muscles crossing the elbow joint according to whether they are medial, lateral, anterior, or posterior to the joint center and identify the actions performed by the muscles listed in the four categories.
Concept introduction: Muscles are soft tissues. Muscles are classified as skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscles contract and relax with the bones and they help in locomotion, gait and respiration. The articulating connection also known as the joint is the connection between two bones that help both the bones to perform the same function in synchronized fashion.

- 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?arrow_forwardWhat muscles are being used in this picture?
