Nervous System

Question 1

Cerebrospinal fluid (CSF)

Answer 1

The floor if the cranial cavity is bone with various ridges. The CSF allows the brain to float in the cranial cavity. Without the CSF, nervous tissue would be damaged by the sheer weight of the brain against the bony floor.

CSF also cushions the brain from impact.

Question 21

Limbic system

Answer 21

Complex of of deep nuclei of cerebrum

Associated with the thalamus and diencephalon 
 INVOLVED in 
Memory( hippocampus)
Emotions ( amygdala) 
Emotional behaviors

Question 22

Diencephalon

Answer 22

Contains the thalamus which acts as a switching station for incoming sensory messages.

Question 23

Hypothalamus

Answer 23

Monitors the interval environment ave helps regulate homeostasis.

Question 24

Thalamus

Answer 24

Serves as a switching station for incoming sensory except those for smell.

It directs the so sorry messages to the appropriate love of the cerebrum.

Question 25

Pons

Answer 25

Large bulge on the anterior surface of the brain stem between the medulla oblongata and the midbrain

Serves as a bridge for motor tracts to the cerebellum

Question 26

Midbrain

Answer 26

The midbrain has FOUR bulges called colliculi on its posterior surface.

• the two superior colliculi are important for visual reflexes.
• the two inferior colliculi are important for auditory reflexes.

Question 27

Reticular formation

Answer 27

Groups of cell bodies called nuclei in the CNS, ganglia in the PNS scattered throughout the brainstem.

The reticular formation is important for arousal.

Responsible for sleep-wake cycles

Question 28

Cerebellum

Answer 28

Second largest brain region
-Inferior to occipital and temporal lobes posterior to pons and medulla oblongata.
- two hemispheres connected by vermis
-outer layer of gray matter surrounding inner white matter called arbor vitae.
-controls and coordinates the interaction of skeletal muscles.
- controls posture balance and muscle coordination
Responsible for reflexive memory.

Question 29

Descending

Answer 29

When your brain thinks of something to do before you do

Question 30

Ascending

Answer 30

Information coming from some type of action to the brain

EX: cut on your foot, neurons send messages to brain to show pain response
