1
Q

What is the human movement system?

A

The combination and interrelation of the nervous, muscular, and skeletal systems.

2
Q

Neurons are composed of 3 main parts, which are:

A

Cell body, Axon, & Dendrites

3
Q

What are Muscle Spindles? Where are they located? And give me an example?

A

Receptors sensitive to change in length of the muscle and the rate of that change. Located in the muscle. When you stretch & realize the stretch.

4
Q

What are Golgi Tendon Organs? Where are they located? And give me an example?

A

Receptors sensitive to change in tension of the muscle and the rate of that change. Located in the tendon. Ex: picking up dumbbell and realizing heaviness.

5
Q

Articulation relates to:

A

Joints. Example: ARTHritis.

6
Q

Axial skeleton:

A

Portion of the skeletal system that consists of the skull, rib cage, and vertebral column.

7
Q

Appendicular skeleton:

A

Portion of the skeletal system that includes the upper and lower extremities.

8
Q

Osteoclasts:

A

A type of bone cell that removes bone tissue. “clear away”

9
Q

Osteoblasts:

A

A type of cell that is responsible for bone formation. “build, form.”

10
Q

Bone markings:

A

They mark bones based on where muscle attaches to the bone.

11
Q

Arthrokinematics:

A

Joint motion.

12
Q

What is altered arthrokinematics?

A

Improper motion of a joint.

13
Q

Tendon attaches:

A

Muscle to bone.

14
Q

Ligament attaches:

A

Bone to bone.

15
Q

Muscular system:

A

Series of muscles that moves the skeleton. “Completes the cycle of movement & production.

16
Q

Actin:

A

Thin filaments.

17
Q

Myosin:

A

Thick filaments.

18
Q

Continuations of tendon that stretch throughout entire muscle:

A

Actin & Myosin.

19
Q

How does muscular contraction occur?

Sliding filament theory

A

By myosin heads attaching to actin and pulling actin towards its counterpart on the sarcomere.

20
Q

Sarcomere:

A

The functional unit of muscle that produces muscular contraction and consists of repeating sections of actin and myosin.

21
Q

Acetylcholine (ACh):

A

Stimulates muscle fibers to go through a series of steps to initiate muscle contraction.

22
Q

All or nothing law:

A

You don’t contract every single muscle fiber half way to lift something heavy. Instead, when you lift something light, you’ll activate a few fibers all the way.

23
Q

Sliding filament theory is the:

A

The theory behind how muscles contract (shorten).

24
Q

What are the 2 muscle fiber types?

A

Type 1 (slow twitch). Type 2 (fast-twitch).

25
Q

Type 1 (slow twitch) characteristics:

A

More capillaries, increased oxygen, smaller in size, less force, SLOW TO FATIGUE, best for endurance based activities (example: postural muscles).

26
Q

Type 2 (fast twitch) characteristics:

A

Fewer capillaries, decreased oxygen, larger in size, more force, QUICK TO FATIGUE, best for power and short term muscular contraction (example: a dunk)

27
Q

Cortisol is a _______ hormone:

A

Catabolic, it breaks down tissues.
