1

What systems make up the Human Movement System

Nervous, Muscular, and Skeletal

2

What system is known as the communication system of the body?

Nervous system- where all movement begins

3

What are the 2 subsystems of the nervous system

CNS and PNS

4

What does the CNS consist of

Brain and Spinal cord

5

Which of the nervous systems subsystems is the primary decision maker

CNS

6

What does the PNS consist of

Nerves from the CNS to the entire body

7

What does the PNS do

Send messages to CNS. Carries out actions from the CNS to the effector sites.

8

What are the 3 types of neurons

Sensory (afferent),interneurons, motor (efferent) neurons

9

Which neurons transmit nerve impulses form effector sites to the brain and spinal cord. These send info from the environment up to the brain

Sensory neurons

10

What do interneurons do?

Transmit nerve impulses from one neuron to another.
Transmits messages from sensory neurons to the motor neurons

11

Which neurons transmit nerve impulses form the brain and spinal cord to effector sites. Sends messages from the brain to the body

Motor (efferent) neurons

12

Name the 3 types of mechanoreceptors

Golgi Tendon organs
Muscle spindles
Joint receptors

13

Which receptor is responsible for sensing tension in muscles and connective tissue and forces muscle to relax

Golgi tendon Organ

14

Which receptor is responsible for sensing length in the muscle and forces the muscle to contract when stimulated?

Muscle spindles

15

Which receptor is responsible for sensing motion, acceleration, and deceleration in the joints. It protects the joints from a compromising situation

Joint receptors

16

Which system is compromised of muscles that work to move and stabilize the body

Muscular system

17

The muscular system is comprised of skeletal muscle tissue whose main function is what

contract on bone to create movement on joints

18

Primary mover of the joint (usually larger muscle)

Agonist

19

Opposing muscle of the prime mover. Decelerates the movement the agonist is producing

Antagonist

20

Lends assistance to the prime mover. Will start to take over for a weak prime mover

Synergist

21

Stabilizes the body and prevents unwanted movements

Stabilizers

22

During a chest press, name the following:
Agonist:
Antagonist:
Synergist:
Stabilizer:

Agonist: Pectoralis major
Antagonist: Posterior deltoid
Synergist:Anterior deltoid and triceps
Stabilizer:Rotator cuff

23

During an overhead press name the following:
Agonist
Antagonist
Synergist
Stabilizer

Agonist: Deltoid
antagonist: Latissimus dorsi
Synergist:Triceps
Stabilizer: Rotator cuff

24

During a squat, name the Agonist, Antagonist, Synergist, and Stabilizer

Agonist: Glutes
Antagonists: Psoas
Synergist: Hamstrings
Stabilizers: Transverse Abs

25

During a row, name the Agonist, antagonist, synergist, and stabilizer muscles

Agonist: Lat dorsi
Antagonist: Pectoralis major
Synergist:Posterior deltoid and biceps
Stabilizer: Rotator cuff

26

Which system is responsible for support, protection, and allowing movement to occur

Skeletal system

27

What are the two functions of the skeletal system

LEVERAGE for our muscles
SUPPORT that directly affects our posture

28

Joint motion

arthokinematics

29

Rolling bone ex

Squat. Femoral condyles roll over tibial condyles

30

Spin bone ex

Head of radius; end of humerus; during pronation and supination

31

Sliding bone ex

tibial slide across femoral in knee extn

32

Cumulative sensory input to the CNS from all mechnoreceptors that sense limb movement and body position

Proprioception

33

A layer of connective tissue that is underneath the fascia and surrounds the muscle

Epimysium

34

Deepest layer of connective tissue that surrounds individual muscle fibers

endomysium

35

Connective tissue that surrounds fasicles

Perimysium

36

Whats the first step in initiating a contraction

ACH is released

37

slow twitch
more capillaries
smaller in size
increased O2
produces less force
Longterm contractions (stabilization)
slow to fatigue

Type 1

38

Fewer capillaries
larger in size
decreased o2
produces greater force
short term contractions (force and power)
quick to fatigue
fast twitch

Type 2

39

Support mechanisms of blood explain

Transportation - transports 02, nutrients to tissues, transports hormones to organs and heat to body
Regulation- body temp and acids
Protection- clotting and infection

40

Ability of the nervous system to sense changes in either the internal or external enviroment

Sensory function

41

Neuromuscular response to sensory info

Motor function

42

Ability of the nervous system to analyse and interpret sensory info to allow for proper decision making which produces the appropriate response

Intergrative function

43

Functional unit of muscle that produces muscular contraction consists of repeating sections of actin and myosin

Sarcomere

44

A motor neuron and all its muscle fibers in innervates

Motor unit

45

Explain what happens to insulin when you exercise
Explain r/s with glucagon

Insulin regulates glucose metabolism by lowering glucose, what isnt used gets stored. Glucagon is a hormone that releases stored gylocgen and converts back to glucose to be used. Exercise decreases insulin , but increase glucagon secretion, therefore maintaining steady levels of blood glucose.

46

Effects of Catecholamines

Increase HR, SV, blood glucose. redistrubtes blood to working tissues and opens up airways
