Somatic Receptors (Sensory receptors)

Answer 7

1. Exteroceptors: External environment
2. Interoreceptors: Internal environment
3. Proprioceptors: Information of body in space.

Question 8

Mechanoreceptors

Answer 8

1. Input received by the skin, muscles, and tendon that facilitate a motor response.
2. Respond to vibration, pressure, tension
   ex. Golgi tendon organs and muscle spindles.

Answer 9

1. Cutaneous receptors
2. Afferent receptors
3. Skin
4. Provides basic info on skin and stretch

Question 10

Golgi tendon organ

Answer 10

1. Tension and contraction and responses relaxation of muscle

Question 11

Muscle Spindle

Answer 11

1. Responds to stretch and responds by contraction of muscle.

Question 12

Joint receptors

Answer 12

1. Activate when muscles move into end ranges of motion.
2. Act more as motion limit detectors
3. Help with basic mid range motion in the fingers

Question 13

Ligaments

Answer 13

1. Ligament stretch inhibit agonist muscle

Question 14

CNS

Answer 14

1. Responds to group of receptors.
2. Must receive input from all sensory, motor, and joint receptors to work together affectively.

Question 15

Neurophysiology

Answer 15

1. Afferent nerves send message to CNS
2. CNS interprets stimuli and initiates limb response

Question 16

CNS

Answer 16

1. Spinal cord
2. Brain stem
3. Cerebral cortex

Question 17

Spinal cord

Answer 17

1. Reflexes
2. Joint quick motion protects body with a quick reflexive contraction
3. Provide joint stability

Question 18

Brain Stem

Answer 18

1. Receives input from proprioceptors, eyes, and ears
2. Assist in maintaining balance
3. Maintains posture and position
4. Vestibular
5. Swtitch board for incoming and outgoing messages

Question 19

Cerebral cortex

Answer 19

1. Conscious movement
2. Controlled movement
3. controlled movement is learned before it becomes automatic

Vestibular

Answer 22

1. Inner ear
   -sick
   
   • concussion
2. Allows the eyes to remain steady when body is on motion

Question 23

Oculomotor system

Answer 23

1. Provides basic feedback of where you are
