0

This part of the brain JOINS the SPINAL CORD to HIGHER PARTS of the brain. It contains FIBER TRACTS ascending and descending to various levels of the CNS.

Medulla

1

The MEDULLA is the place of EXIT and ENTRANCE for cranial nerves ___ through ___.

V-XII

2

The MEDULLA contains AUTONOMIC nuclei concerned with __________, __________ and ___________.

Breathing, Blood Pressure and Heartbeat

3

The MEDULLA is also known as...

The Vital Center of the Brain

4

This is the organ of MOTOR COORDINATION.

Cerebellum

5

This is the portion of the CEREBELLUM that receives FIBERS that have been relayed from the SENSE ORGANS of EQUILIBRIUM.

Ventral Portion

6

These portions of the CEREBELLUM are supplied chiefly with SENSORY fibers from the SPINAL CORD.

Anterior and Posterior

7

This portion of the CEREBELLUM has extensive CONNECTIONS with nuclei of the PONS and FRONTAL CORTEX.

Neocerebellum

8

This part of the HINDBRAIN CONNECTS the hindbrain and FOREBRAIN.

Midbrain

9

This is known as the "FLOOR" of the MIDBRAIN and serves mainly as a PASSAGEWAY.

Tegmentum

10

This is known as the "ROOF" of the MIDBRAIN and had TWO PAIRS of SENSORY CENTERS.

Tectum

11

This PAIR of SENSORY CENTERS of the TECTUM are the primitive VISUAL CENTERS.

Superior Colliculi *Fig 3.21 p. 66*

12

This PAIR of SENSORY CENTERS of the TECTUM are the primitive AUDITORY CENTERS.

Inferior Colliculi *Fig 3.21 p. 66*

13

This component of the brain OVERLAPS the FOREBRAIN, MIDBRAIN and HINDBRAIN. It AROUSES the CEREBRAL CORTEX.

Reticular Formation *Fig 3.2 p. 66*

14

This COMPONENT of RETICULAR FORMATION constitutes 1 of 2 routes traveled by SENSORY IMPULSES on the way to the CEREBRAL CORTEX.

Ascending Component

Arouses cerebral cortex

15

This COMPONENT of RETICULAR FORMATION functions in MOTOR COORDINATION.

Descending Component

16

This is the GREAT RELAY CENTER located in the DIENCEPHALON of the FOREBRAIN.

Thalamus

17

All senses EXCEPT _________ send impulses to the THALAMUS on their way to the cortex

Olfaction

18

This PROJECTION NUCLEUS of the THALAMUS is involved in SOMETHESIS, KINESTHESIS and TASTE.

Posteroventral Nucleus

19

This PROJECTION NUCLEUS of the THALAMUS is part of the LIMBIC SYSTEM.

Anterior Nucleus

20

This PROJECTION NUCLEUS of the THALAMUS received IMPULSES from RETICULAR FORMATION.

Reticular Nucleus

21

The LATERAL geniculate nucleus (LGN) is involved in ________.

Vision

22

The MEDIAL geniculate nucleus (MGN) is involved in __________.

Audition

23

The LATEROVENTRAL nucleus RECEIVES impulses from the__________ and SENDS impulses to the_________.

FROM Cerebellum
TO Cerebral cortex

24

The ASSOCIATION nuclei RECEIVE impulses from within the __________ and SEND impulses to the __________.

FROM Thalamus
TO Cortex

25

These ASSOCIATION nuclei PROJECT toward the FRONTAL CORTEX.

Dorsalmedial Nuclei

26

This nucleus PROJECTS to the POSTERIOR CORTEX.

Pulvnar Nucleus

27

This part of the DIENCEPHALON is involved in the regulation of BASIC DRIVES like hunger and thirst.

Hypothalamus

28

True or False: the HYPOTHALAMUS controls/integrates functions of the somatic NS.

FALSE, the HYPOTHALAMUS controls and integrates functions of the AUTONOMIC NS.

29

The HYPOTHALAMUS is involved in _____________ and ________.

Endocrine Secretions

Motion

30

This is a part of the CORPUS SRTIATUM and located in the TELENCEPHALON.

Basal Ganglia

*Fig 3.28 p.71*
*Fig 15.7 p. 385*

31

The BASAL GANGLIA consists of THREE LARGE NUCLEI called __________, __________ and __________.

1.) Caudate Nucleus
2.) Putamen
3.) Globus Pallidus


*Fig 3.28 p.71*
*Fig 15.7 p. 385*

32

The BASAL GANGLIA RECEIVES input from the _____________ and cerebral cortex, then sends messages to the midbrain and cerebral cortex.

Substantia Nigra

*Fig 3.28 p.71*
*Fig 15.7 p. 385*

33

Phylogenetically, the CAUDATE NUCLEUS, PUTAMEN and GLOBUS PALLIDUS are the newest parts of the telencephalon.

FALSE, they are the OLDEST parts of the telencephalon

*Fig 3.28 p.71*
*Fig 15.7 p. 385*

34

Degeneration of neurons that contain DOPAMINE and link substantia nigra to basal ganglia leads to ______________, characterized by TREMORS AT REST.

Parkinson's Disease

*Fig 3.28 p.71*
*Fig 15.7 p. 385*
