1
Q

Myology

A

the study of the nature, structure, function, and diseases of the muscle.

2
Q

Muscular System

A

covers, shapes, and supports the skeletal tissue. Contacts and moves various parts of the body. The human body has over 630 muscles, which is responsible for about 40% of the body’s weight. 30 of them are facial muscles. Muscles are fibrous tissues with the ability to stretch and contract according to the demands of the body’s movements.

3
Q

Striated muscles

A

AKA skeletal or voluntary, attached to the bones and make up a large percentage of body mass and are controlled by the wall. Nerve impulses trigger a reaction from the muscle which contracts, moving its associated bone or joint.

4
Q

Nonstriated muscles

A

AKA involuntary, visceral, or smooth, functions automatically, without conscious will. These muscles are found in the digestive and circulatory systems as well as some internal organs of the body.

5
Q

Cardiac muscle

A

the involuntary muscle that makes up the heart. This type of muscle is unique and not found in any other part of the body. It is striated and has a crossing, banding pattern that allows contraction and thus the beating of the heart. It is under the control of the autonomic nervous system.

6
Q

Origin

A

the more fixed part of the muscle closest to the skeleton, which flexes, but remains stationary.

7
Q

Belly

A

middle part of the muscle

8
Q

Insertion

A

part of the muscle which is the movable attachment and furthest from the skeleton. Pressure in massage is usually directed from the insertion to the origin.

9
Q

There are 7 ways to stimulate muscle tissue. Name all 7.

A
  • Massage (hand or electric vibrator)
  • Electrical therapy current (chap. 8)
  • Light rays (infrared light, light-emitting diode [LED] or UV)
  • Heat rays (heating lamps or heating caps)
  • Moist heat (steamers or moderately warm steam towels)
  • Nerve impulses (through the nervous system )
  • Chemicals (certain acids and salts)
