Q

Peripheral nervous system (PNS)

A

Nerves and peripheral ganglia

17
Q

Meninges

A

3 layers of tissue that encase the CNS

  • keeps fluid in the system
  • maintains space to prevent concussion
18
Q

Ventricles

A

Hollow space w/in brain

Filled w/ cerebrospinal fluid

19
Q

Cerebrospinal fluid (CSF)

A

Clean fluid fills the ventricles and subarachnoid space

  • chemical stability
  • clearing waste
20
Q

Telencephalon

A

Cerebral cortex
Limbic system
Basal ganglia

21
Q

Cerebral cortex

A

Part of Telencephalon

Cortical lobes
Corpus callosum
Neocortex
Primary sensory cortices

22
Q

Limbic system

A

Part of Telencephalon

Amygdala
-emotion

Hippocampus
-memory

Limbic cortex

  • olfaction
  • reward
  • “lower animal cortex”

Fornix
-bundle of fibers carrying info from hippo to hypo

Mammillary body
-episodic memory
Possible adds odor to memories

23
Q

Basal ganglia

A

Part of Telencephalon

3 parts

  1. caudate nucleus
  2. globus pallidus
  3. putamen

Imp. for motor control

24
Q

Diencephalon

A

Thalamus

Hypothalamus

25
Thalamus
Part of Diencephalon ``` Motor control Relays sensory (except olfaction) info to cortex Regulates sleep & wake cycles Appears to be involved in consciousness Motor movement ```
26
Hypothalamus
Part of Diencephalon ``` Thermoregulation Circadian rhythms Thirst/hunger Reproduction Parental/partner attachment ```
