Answer 1

• usually results from a spinal cord injury.
• the loss of normal SNS tone and vasodilation
  -muscles in the walls of the blood vessels are cut off from nerve impulses that usually cause them to contract

bowel and bladder activity (S2-S3)

Question 11

about the spine

Answer 11

-33 vertebrae
- stabilized by ligaments and muscles
- allow for fluid movement and erect stature

Question 12

spinal locations

Answer 12

cervical, thoracic, lumbar, sacral, coccyx

Question 13

vertebrae components

Answer 13

vertebral body, lamina, pedicles, spinous processes

Question 14

CSF

Answer 14

bathes the brain and spinal cord, provides cushion for the central nervous system

Question 15

ascending tract

Answer 15

carry information to the brain

Question 16

descending tract

Answer 16

carry information away from the brain

Question 17

the spinal cord

Answer 17

extends from the base of the skull to L2
- transmits nerve impulses between the brain and the rest of the body

Question 18

posterior (dorsal) horn

Answer 18

sensory input

Question 19

anterior (ventral) horn

Answer 19

motor input

Question 20

autonomic nervous system Is divided into what nervous systems

Answer 20

sympathetic and parasympathetic

Question 21

SNS

Answer 21

• controlled by the hypothalamus in the brain
• governs our fight or flight response
• responsible for: sweating, pupil dilation, temp regulation, shunting of blood from the periphery to the core

Question 22

disruption of SNS communication can cause

Answer 22

• disruption of homeostasis, leaving the body unable to cope with environmental changes
• autonomic dysreflexia dues to sympathetic overdrive
• cause life threatening hypertension

Question 23

6 B’s that are the common causes of autonomic dysreflexia

Answer 23

bladder, bowel, back passage, boils, bones, babies

Question 24

PNS

Answer 24

• carries signals from the brainstem and upper spinal cord to the organs and skin above the waist
• the vagus nerve travels from outside the medulla to the heart via the carotid arteries, thus vagus tone remain intact following a spinal injury
