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.

Cite example for each movement. (Ex. for ADDUCTION- Bringing fingers together from a spread wide apart position) Flexion Extension Abduction Adduction Rotationarrow_forwardLocate 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_forward

(hint: there are quite a few – write down each joint movement and the muscles that are responsible)arrow_forwardSeveral criteria were given for the naming of muscles. Match the muscle names (column B) to the criteria (column A). Note that more than one muscle may fit the criterion in some cases Column A action of the muscle 2 shape of the muscle 3 location of the origin and/or insertion of the muscle 4 number of origins 5 location of the muscle relative to a bone or body region 6 direction in which the muscle fibers run relative to some imaginary line 7 relative size of the muscle Column B abdominis transversus biceps brachiideltoid erector spinaeexternal intercostalsflexor digitorum superficialis pectoralis majorrectus abdominisarrow_forwardMuscles work in groups when they perform multifaceted movements. Write the anatomical term that describes the muscle of a compartment that performs the following action. 1. M uscle that is opposing an action 2. Muscle that stabilizes the origin of a prime mover 3.

- To do Left elbow supination in the Horizontal plane, the ( name the muscle ) would have to lie (A – Where?) relative to the joint, and since it can only (PULL), the fibers would have to run (PERPENDICULAR ) to the (D ) axis to achieve the desired movement. choose from: A. Pick from: Anterior, Posterior, Medial, Lateral, Superior, Inferior B. Write in the word “PULL” C. Write “perpendicular” D. Pick from :Anterior - posterior, Superior-inferior or Medio - Lateral Example:arrow_forwardList each muscle name or muscle combination/group name only once in the table below.arrow_forwardIdentify the joint actions caused by the concentric contractions of the following muscles.

Some will be a group of muscles, and others will be a single large muscle.arrow_forwardIdentify the muscles that are involved in the following movements: Knee Extension Knee Flexsion Knee Fytenarrow_forward1) Describe the different criteria that contribute to how skeletal muscles are named. For example you can use the names of the muscles below to predict their location, action or appearance: Abdominal external oblique, Trapezius, Flexor carpi ulnaris, Gastrocnemius 2) Describe the muscles of the anterior abdominal wall. 3) Why are the muscles of the face different from typical skeletal muscle?arrow_forward
