Flashcards in Chapter 13 (part 2) Deck (35):
1

Links cerebral hemispheres and rest of CNS

Diencephalon

2

Process and relay appropriate information to the appropriate cortex, filters information and allows focusing

Thalamus

3

Relays signals from limbic system to midbrain and regulates visceral and emotional responses to odors

Epithalamus

4

Secretes melatonin hormone for regulating circadian rhythm

Pineal gland

5

Controls autonomic and endocrine system, thermoregulation, emotional behavior, hunger, thirst, release of melatonin

Hypothalamus

6

Secretes variety of hormones

Pituitary gland

7

Controls feeding reflexes

Mammillary bodies

8

Passageway for all tracts between brain and spinal cord

Brainstem

9

What are the 3 components of the brainstem?

Midbrain, pons, medulla oblongata

10

Relay sensory and motor info, produce neurotransmitters for movement and emotion, issue involuntary commands to postural muscles, relay visual/auditory info and coordinates reflexes to them

Midbrain

11

Relay sensory and motor info, locate sound, adjust respiratory activity

Pons

12

Relay sensory and motor info, coordinate autonomic responses for heart rate/ contraction, blood pressure and distribution of blood, breathing rates

Medulla oblongata

13

Coordinates/tweaks movements to smooth them out, store memories of movement patterns, receive and interpret proprioceptive info, adjust skeletal muscle activity to maintain balance

Cerebellum

14

Establish emotional state, link conscious and unconscious function, role in memory storage/retrieval, control flight or fight response, link emotion with memory

Limbic system

15

What makes up the limbic system?

Diencephalon, cingulate gyrus, olfactory tract

16

Regulate muscle tone, assist in autonomic function, mental alertness

Reticular formation

17

What makes up the reticular formation?

Midbrain, pons, medulla oblongata

18

Responsiveness, self-aware, well-oriented to person, place, and time

Alertness

19

Protective connective tissue layers which are continuous from brain to spinal cord

Meninges

20

Separate soft brain tissue to skull, enclose and protect, contain and separate CSF

Meninges

21

Innermost layer directly attached to neural tissue

Pia mater

22

What is pia mater made of?

Areolar connective tissue

23

Middle layer of meninges

Arachnoid mater

24

What are the 2 components of arachnoid mater?

Arachnoid membrane, subarachnoid space

25

Space below arachnoid membrane and between processes filled with CSF

Subarachnoid space

26

Outermost layer

Dura Mater

27

What are the 2 layers of dura mater?

Superficial periosteal layer, deep meningeal layer

28

What is dura mater made of?

Dense irregular connective tissue

29

Temporary absence of consciousness from which a person can be aroused by normal stimulation

Sleep

30

What are the 2 types of sleep?

Non-REM, REM

31

What is lack of sleep associated with?

Depression, impaired memory, decreased immune function

32

Associating sensory input that lasts seconds

Sensory memory

33

Limited capacity and brief duration

Short-term memory

34

What does short term memory use?

Hippocampus

35

Requires adequately repeating, addressing, and organizing information from short-term memory

Long-term memory
