Nervous system quiz 2 study guide Flashcards
Central nervous system
brain and spinal cord
Autonomic Nervous System
the part of the pns that controls glands and the muscles of internal organs
peripheral Nervous system
the sensory and motor neurons that connect the central nervous system to the rest of the body
Cerebrospinal fluid
- fluid in the space between the meninges
- acts as a shock obsober
- protects the central nervous system
Cerebrum
Area of brain responsible for all voluntary activities of the body
brain stem
responsible for automatic survival functions
Medulla Oblongata
part of the brainstem that controls vital life sustaining actions such as the heartbeat, breathing, blood pressure, and digestion
Hypothalamus
- a nueral structure lying below the thalamus
- directs eating, drinking, body temp
- helps govern the endocrine system via the pituitary gland
- linked to emotion
Cerebellum
balance and coordination
Spinal nerve
31 pairs of nerves arising from the spinal cord
Meninges
3 protective membranes that suround the brain and spinal cord
Ventricles
cerebral spinal fluid filled cavities within the brain
Thalamus
1.the brains sensory switchboard
2. located at the top of the brainstem
3. it directs messages to the sensory recieving area in the cortex
4.transmits replies to the cerebellum and medulla
Pons
a brain structure that relays info from the cerebellum to the rest of the brain
Corpus Callosum
- a thick band of axons that connect the 2 cerebral hemispheres
- acts as comunication link between them
Gyri
ridges/folds of the brain
Sulci
shallow grooves of the brain
Frontal lobe Description
- located in the front of the brain
2.Responsible for higher level cognitive functions
ex. planning, decisions, speach
Name 3 areas of cerebrum
- Frontal lobe
- parietal lobe
- Temporal Lobe
Temporal lobe description
1.located on the sides of the brain
2. auditory processing, memory formation, language comprehension
parietal lobe description
- Situated behind the frontal lobe
- processes sensory info
ex. touch, temp, Pain
2 cranial nerve and their functions
