Q

Human Movement System

A

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

2
Q

Neuron

A

The functional unit of the

nervous system.

3
Q

Motor Function

A

The neuromuscular
response to the sensory
information.

4
Q

Proprioception

A

The ability to sense body position and limb movement relative to adjacent parts of the body and the environment

5
Q

Mechanoreceptors

A

Sensory receptors responsible for sensing distortion in body tissues

6
Q

Golgi Tendon Organs

A

Receptors sensitive to change and rate of change of tension

7
Q

Muscle Spindles

A

Receptors sensitive to change in length of the muscle and rate of that change

8
Q

Joint Receptors

A

Receptors that respond to pressure, acceleration, and deceleration in the joint

9
Q

Nervous System

A

the body’s communication network, gathers and interprets information, and determines all movement

10
Q

What are the three functions of the nervous system?

A

Sensory, integrative, and motor

11
Q

What are 4 benefits to training proprioceptive abilities?

A

Improved balance, posture, coordination, and the ability to adapt to changing environments

12
Q

Motor (efferent) neurons

A

Transmits nerve impulses from the CNS to effector sites in muscles or organs

13
Q

Central Nervous System

A

consists of brain and spinal cord

14
Q

Peripheral NS

A

Cranial and spinal nerves that spread throughout the body

15
Q

Ligaments

A

connective tissue that connects bones together and provides stability and input to the nervous system

16
Q

Long Bone

A

Bone with a cylindrical body (shaft) that are longer than they are wide and enlarge and widen at each end

17
Q

Arthrokinematics

A

The motions of the joints in the body

18
Q

What are the 3 types of joint motion?

A

Roll, slide, and spin

19
Q

What are the 6 types of joints related to movement?

A

What are the 6 types of joints related to movement?Gliding, condyloid, hinge, saddle, pivot, and ball-and-socket

20
Q

Most-mobile joints that allow motion in all three planes

A

Ball and Socket

Q

What percentage of the population experience low back pain?

A

4/5

22
Q

What type of joint primarily moves in one plane of motion?

A

Hindge

23
Q

What layer of connective tissue is underneath the fascia and surrounds the muscles?

A

Epimysium

24
Q

A

DELTOIDS

25
Q

Synergist

A

secondary/assister to prime mover

26
Q

Agonist

A

main mover of an exerise

27
Q

Catabolic Hormons

A

Break Down; cortisol and Glucagon

28
Q

Anabolic Hormones

A

Build up; Insulin and testosterone

29

A

7

30
Q

How many bones in the thoracic region?

A

5

31
Q

How many bones in the lombard region?

A

5

32
Q

Epimyosium

A

sheath of connective tissue surrounding the muscle

33
Q

Type 1 Muscle Fibers

A

SLOW TWITCH
Aerobic/Oxidative (uses fat as fuel)
smaller, more endurance, more blood flow, 12+ repetitions
ex: an athlete would be a long distance runner
ex of muscle primarily composed of type 1 muscle fibers: heart and calves

34
Q

Type 2 Muscle Fibers

A

FAST TWITCH
Anaerobic (uses carbs are fuel), larger, power and force production, QUICK to fatigue, LESS blood flow, 1-12 reps
ex of athlete: lifter/sprinter/b-ball player
ex of muscle: quads and chest

35
Q

Fascicle

A

bundle of muscle fibers

36
Q

A

Basic unit is Osteon.
206 bones of which 126 are part of the appendicular (freely moving bones ex: femur)
80 bones are within the AXIAL (fixed skeleton ex: sternum)
