1

Sensory receptors responsible for sensing distortion in body tissues

Mechanoreceptors

2

Receptors sensitive to change and rate of change of tension

Golgi tendon organs

3

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

Muscle spindles

4

The functional unit of the nervous system

The neuron

5

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

Joint receptors

6

The system that acts as the body’s communication network, gathers and interprets information, and determines all movement

Nervous system

7

What are the three functions of the nervous system?

Sensory, integrative, and motor

8

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

Proprioception

9

What are the four benefits to training proprioceptive abilities?

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

10

What are the three main parts of a neuron?

Cell body, Axon, dendrites

11

Transmit nerve impulses from receptors in tissues to the CNS

Sensory (afferent) neurons

12

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

Motor (efferent) neurons

13

Transmits nerve impulses from one neuron to another

Interne Urins

14

The portion of the nervous system consists of the brain and the spinal cord

Central nervous system

15

Cranial and spinal nerves that spread throughout the body

Peripheral nervous system

16

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

Ligaments

17

Flattened or indented portion of bone which can be a muscle attachment site

Depression

18

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

Axial skeleton

19

Portion of the skeletal system that includes the bones that connect to the spinal column including the upper and lower extremities

Appendicular skeleton

20

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

Long bone

21

Cube or box shaped bones that are nearly as wide as they are long; made out of mostly sponge bone tissue to maximize shock absorption

Short bones

22

Thin bones made of two layers of compact bone tissue around a layer of spongy bone tissue

Flat bone

23

Bones of unique shape and function that do not fit the characteristics of other categories

Irregular bones

24

Small, often round bones embedded in a joint capsule

Sesamoid bones

25

The motions of the joints in the body

Arthrokinematics

26

What are three types of joint motion?

Roll, slide, and spin

27

What are the six types of joints related to movement?

Gliding, condyloid, pivot, and ball-and-socket

28

Joints held together by a joint capsule and ligaments; most associated with movement in the body

Synovial joints

29

Most mobile joints that allow motion in all three planes

Ball-and-socket

30

What does bone do in response to progressive exercise

Gets stronger

31

What can prevent bone injuries related to falls?

Maintaining muscle strength, coordination, and balance

32

What is the best exercise to help strengthen bone?

Weight-bearing exercise

33

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

Sacromere
