Describe the actions of muscles when they contract, and define the terms agonist and antagonist in muscle action.

Expert Solution & Answer

Summary Introduction

To review:

The actions of contracted muscles and the definitions of antagonist and agonist involved in muscle action.

Introduction:

The skeletal muscles are composed of muscle fibers and activated by somatic motor neuron that results in the contraction of these muscles leading to their movement. The skeletal muscles are joined to the bones at both ends through tendons (connective tissue). The contraction and relaxation result in different movements of the body.

Explanation of Solution

The skeletal muscle contraction results in various actions or movements that depend upon the type of joints and attachments present within the muscles. Different actions that are seen during the contraction of different muscles are given below:

Agonist- Agonist provides the major force to complete the movement. They are also known as â€˜prime moversâ€™of skeletal muscles and cause movement through their own activation.

Antagonist- In antagonist muscles, the contraction is done by the involvement of two muscles such as flexor and extensor whict act on the same muscle (as agonist) causing the opposite action.

You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.

Describe the actions of muscles when they contract, and define the terms agonist and antagonist in muscle action.

Expert Solution & Answer

Summary Introduction

To review:

The actions of contracted muscles and the definitions of antagonist and agonist involved in muscle action.

Introduction:

The skeletal muscles are composed of muscle fibers and activated by somatic motor neuron that results in the contraction of these muscles leading to their movement. The skeletal muscles are joined to the bones at both ends through tendons (connective tissue). The contraction and relaxation result in different movements of the body.

Explanation of Solution

The skeletal muscle contraction results in various actions or movements that depend upon the type of joints and attachments present within the muscles. Different actions that are seen during the contraction of different muscles are given below:

Agonist- Agonist provides the major force to complete the movement. They are also known as â€˜prime moversâ€™of skeletal muscles and cause movement through their own activation.

Antagonist- In antagonist muscles, the contraction is done by the involvement of two muscles such as flexor and extensor whict act on the same muscle (as agonist) causing the opposite action.
