The Brain Flashcards
The MEDULLA is the place of EXIT and ENTRANCE for cranial nerves ___ through ___.
V-XII
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
The MEDULLA contains AUTONOMIC nuclei concerned with __________, __________ and ___________.
Breathing, Blood Pressure and Heartbeat
The MEDULLA is also known as…
The Vital Center of the Brain
This is the organ of MOTOR COORDINATION.
Cerebellum
This is the portion of the CEREBELLUM that receives FIBERS that have been relayed from the SENSE ORGANS of EQUILIBRIUM.
Ventral Portion
These portions of the CEREBELLUM are supplied chiefly with SENSORY fibers from the SPINAL CORD.
Anterior and Posterior
This portion of the CEREBELLUM has extensive CONNECTIONS with nuclei of the PONS and FRONTAL CORTEX.
Neocerebellum
This part of the HINDBRAIN CONNECTS the hindbrain and FOREBRAIN.
Midbrain
This is known as the “FLOOR” of the MIDBRAIN and serves mainly as a PASSAGEWAY.
Tegmentum
This is known as the “ROOF” of the MIDBRAIN and had TWO PAIRS of SENSORY CENTERS.
Tectum
This PAIR of SENSORY CENTERS of the TECTUM are the primitive VISUAL CENTERS.
Superior Colliculi Fig 3.21 p. 66
This PAIR of SENSORY CENTERS of the TECTUM are the primitive AUDITORY CENTERS.
Inferior Colliculi Fig 3.21 p. 66
This component of the brain OVERLAPS the FOREBRAIN, MIDBRAIN and HINDBRAIN. It AROUSES the CEREBRAL CORTEX.
Reticular Formation Fig 3.2 p. 66
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
This COMPONENT of RETICULAR FORMATION functions in MOTOR COORDINATION.
Descending Component
This is the GREAT RELAY CENTER located in the DIENCEPHALON of the FOREBRAIN.
Thalamus
All senses EXCEPT _________ send impulses to the THALAMUS on their way to the cortex
Olfaction
This PROJECTION NUCLEUS of the THALAMUS is involved in SOMETHESIS, KINESTHESIS and TASTE.
Posteroventral Nucleus
This PROJECTION NUCLEUS of the THALAMUS is part of the LIMBIC SYSTEM.
Anterior Nucleus
This PROJECTION NUCLEUS of the THALAMUS received IMPULSES from RETICULAR FORMATION.
Reticular Nucleus
The LATERAL geniculate nucleus (LGN) is involved in ________.
Vision
The MEDIAL geniculate nucleus (MGN) is involved in __________.
Audition
The LATEROVENTRAL nucleus RECEIVES impulses from the__________ and SENDS impulses to the_________.
FROM Cerebellum
TO Cerebral cortex
The ASSOCIATION nuclei RECEIVE impulses from within the __________ and SEND impulses to the __________.
FROM Thalamus
TO Cortex
These ASSOCIATION nuclei PROJECT toward the FRONTAL CORTEX.
Dorsalmedial Nuclei
This nucleus PROJECTS to the POSTERIOR CORTEX.
Pulvnar Nucleus
This part of the DIENCEPHALON is involved in the regulation of BASIC DRIVES like hunger and thirst.
Hypothalamus
True or False: the HYPOTHALAMUS controls/integrates functions of the somatic NS.
FALSE, the HYPOTHALAMUS controls and integrates functions of the AUTONOMIC NS.
The HYPOTHALAMUS is involved in _____________ and ________.
Endocrine Secretions
Motion
This is a part of the CORPUS SRTIATUM and located in the TELENCEPHALON.
Basal Ganglia

The BASAL GANGLIA consists of THREE LARGE NUCLEI called __________, __________ and __________.
- ) Caudate Nucleus
- ) Putamen
- ) Globus Pallidus
- Fig 3.28 p.71*
- Fig 15.7 p. 385*
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*
Phylogenetically, the CAUDATE NUCLEUS, PUTAMEN and GLOBUS PALLIDUS are the newest parts of the telencephalon.
FALSE, they are the OLDEST parts of the telencephalon

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