Question 9 of 25

1

What is a muscle?

Select one or more of the following:

Skeletal muscles are voluntary; they function in the horses movement.

Explanation

Question 11 of 25

These muscles are involuntary, or autonomic; they play a part in the digestive, respiratory, circulatory, and urogenital systems.

Select one or more of the following:

Cardiac and Smooth Muscles
Skeletal and Cardiac Muscles

Cardiac and Skeletal Muscles

Explanation

Question 12 of 25

Explanation

Question 13 of 25

1

The Muscle Spindle and the Golgi Apparatus are the same thing.

Select one of the following:

True
False

Explanation

Question 14 of 25

1

Nerve endings of the muscle spindle prevent overstretching of the muscle fibers.

Select one of the following:

True
False

Explanation

Question 15 of 25

1

What are the two types of sensory nerve endings?

Select one of the following:

Origin Tendon and Insertion Tendon
Fast Twitch Fibers and Slow Twitch Fibers
Golgi Apparatus and Muscle Spindle

Explanation

Question 16 of 25

1

What is the Golgi Apparatus?

Select one of the following:

Seals the capsular ligament (Joint Capsule) which produces a viscous, lubricating, secretion.
One of two types of sensory nerve endings in the muscles. Nerve endings of this prevent over stretching of the muscle fibers. This nerve fiber coils around the length of the muscle bundle.
One of two types of sensory nerve endings in the muscles. These nerve endings send feedback impulses to the brain as to the whereabouts of the muscles, this process is referred to as proprioception (being aware of the body and its actions)

Explanation

Question 17 of 25

1

What is a contracture?

Select one of the following:

Connective tissue that covers, supports and separates the muscle bundles and the whole muscle itself.
A dense white fibrous tissue, much like that of a ligament.
The portion of the muscle that attaches to the bone.
When the muscles do not release, staying contracted, resulting in a spasm.

Explanation

Question 18 of 25

1

Fast Twitch Fibers are....

Select one of the following:

AEROBIC FIBERS; they NEED oxygen in order to do their job. They also have strong endurance qualities. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.
ANAEROBIC FIBERS; they DO NOT need oxygen to work and are therefore able to deliver the quick muscular effort required for a sudden burst of speed. They are only able to perform for a short amount of time. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.

Explanation

Question 19 of 25

1

Slow Twitch Fibers....

Select one of the following:

Are ANAEROBIC FIBERS; they DO NOT need oxygen to work and therefore able to deliver the quick muscular effort required for a sudden burst of speed. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.
Are AEROBIC FIBERS; they need oxygen in order to do their job. They require a good supply of blood to bring oxygen to them and to remove waste products created during exercise. ST and FT are genetically inherited, some breeds are bred specifically for their tendency to have more slow twitch or fast twitch fibers. Ex. ST- Draft Horse, for endurance. FT - Quarter horse, for speed.

Explanation

Question 20 of 25

1

What is connective tissue?

Select one of the following:

Covers, supports, and separates the muscle bundles and the whole muscle itself.
A dense, white, fibrous tissue, much like that of a ligament.

Explanation

Question 21 of 25

1

What is Fascia?

Select one of the following:

A dense white fibrous tissue, much like that of a ligament.
Covers, supports and separates the muscle bundles and the whole muscle itself. This arrangement allows for greater support, strength, and flexibility in the movement between each of the muscle groups.
Muscles are attached to the bone by Fascia.

Explanation

Question 22 of 25

1

What attaches bone and muscles together?

Select one of the following:

Fascia
Tendons
ligaments

Explanation

Question 23 of 25

1

What does the Insertion Tendon do?

Select one of the following:

Attaches the muscle to the least movable bone
Attaches the muscle to the movable bone, so that on contraction the insertion is brought closer to the origin.

Explanation

Question 24 of 25

1

What is the Origin Tendon?

Select one of the following:

Attaches the muscle to the movable bone, so that on contraction the insertion is brought closer to the origin.
Attaches the muscle to the least movable bone.
