Flashcards in Human Movement System (Ch3) Deck (39):
1

The Human Movement System is made up what three interconnected components?

Nervous, Muscular and Skeletal systems.

2

The Human Movement System is also called what?

Kinetic Chain

3

Tells the musculoskeletal system of the body when and how to move. Collects all sensory information and sends a movement for response.

Nervous System

4

Includes brain and spinal cord and its primary function is to coordinate activity in all parts of the body.

Central Nervous System

5

Includes nerve fibers that branch out from CNS and extend to the body.

Peripheral Nervous System

6

Functional unit of the nervous system. Mad e of three parts: cell body, axon, and dendrites.

Neuron

7

Sensory receptors that respond to a change in the position of body position and limb movements.

Mechanoreceptors

8

Cumulative sensory input to the CNS from all mechanoreceptors. Awareness and perception of body position and limb movements. What allows a person to close their eyes and still touch a finger to their nose.

Proprioception

9

Receptors sensitive to to change in length of the muscle and rate of that change. Found in skeletal muscles.

Muscle Spindles

10

Receptors sensitive to amount and rate of tension tension that develops in the muscle.

Golgi tendon organs (GTO)

11

Receives messaging from the brain to shorten or lengthen, creating movement to the skeletal system.

Muscular System

12

Muscles are made of up fibers with smaller tubes held within called ____.

Myofibrils

13

__________ contain long proteins called filaments that slide past each other to produce muscular contractions.

Sarcomeres

14

A single contraction of a facilitated muscle

a twitch

15

slow-twitch fibers.
considered highly aerobic.
more resistant to fatigue.
smaller in size.

Type I Fibers

16

fast-twitch fibers.
considered more anaerobic.
more speed and strength, but burst of intensity is short lived.
larger in size.

Type II Fibers

17

Meaning "with oxygen", the long-term energy production cycle that occurs when sufficient oxygen is present.

Aerobic

18

Meaning "without oxygen", the short-term energy production cycle that occurs with insufficient oxygen levels.

Anaerobic

19

Muscle that works as the prime mover of a joint exercise.

Agonist

20

Muscles that assist the prime mover in a joint exercise.

Synergists

21

Muscle's 4 behavioral properties that help facilitate movement.

Extensibility

22

Connective tissues connecting bone to bone

Ligaments

23

Connective tissue attaching muscle to bone

Tendons

24

Restricting an opposite motion

Reciprocal Inhibition

25

When we consume food and transform it into usable energy it is in the form of _______.

ATP

26

- Occurs during the first 10-15 seconds of activity
- Anaerobic
- Used for activities that require high power or strength

ATP-PC system

27

3 pathways to energy

ATP-PC system
Glycolysis
Aerobic Processes

28

- Occurs during first 2-3 minutes of activity
- Glucose without presence of oxygen (anaerobic) to create ATP

Glycosis

29

Used in any activity lasting longer than 2-3 minutes

Aerobic Processes

30

Blood production is part of which system?

(A) Nervous System
(B) Muscular System
(C) Skeletal System

C) Skeletal System

33

Energy storage and transfer units within the cells of the body are called _______

Adenosine triphosphate

34

Refers to the amount of blood pumped out of the heart with each contraction

Stroke Volume

35

A muscle that is commonly overactive in the foot and ankle

Soleus

36

The synergistic action of muscle groups to produce movement around a joint

Force-couple

37

Which of the following is true of the Golgi tendon organ when excited?
Select one:
a. It causes a muscle to lengthen.
b. It causes a muscle to relax.
c. It causes a muscular contraction.
d. It results in micro muscle spasms.

b. It causes a muscle to relax.

38

Relaxation of the psoas so the glutes can contract is an example of what?

Reciprocal Inhibition
