PHYSIOLOGY II EXAM | QUESTIONS AND
VERFIED ANSWERS RATED A+ |
CHAMBERLAIN
CSF - Correct Answer - cerebrospinal fluid
what does CSF do? - Correct Answer - Provides protection against brain
compression, chemical protection, and provides nutrients to the brain.
How is CSF produced? - Correct Answer - plasma is drawn from the
choroid plexuses through ependymal cells into the ventricles to produce
CSF
How does CSF flow? - Correct Answer - Arteries -> choroid plexus ->
ventricles (higher pressure) -> follows apertures to subarachnoid spaces
-> arachnoid granules (to venous return, lowest pressure)
How is the brainstem divided? - Correct Answer - Midbrain, Pons,
Medulla
What is the midbrain responsible for? - Correct Answer - vision and
hearing
What is the pons? - Correct Answer - the part of the brainstem that links
the medulla oblongata and the thalamus.
,What is the medulla oblangata? - Correct Answer - The base, controls
unconscious activities like breathing, movement in the intestines and
heartbeat
What cranial nerves are associated with midbrain? - Correct Answer -
CN III and IV(3 and 4)
what cranial nerves are associated with pons? - Correct Answer - V, VI,
VII, VIII (5,6,7,8)
what cranial nerves are associated with medulla? - Correct Answer - IX,
X, XI, XII (9,10,11,12)
What is riticular formation? - Correct Answer - involved in the sleep and
wake cycle arousing you from sleep and maintaining consciousness.
Helps maintain muscle tone.
Cerebellum - Correct Answer - A large structure of the hindbrain that
controls fine motor skills.
-Posterior to pons
- divides cerebrum and brainstem
-Connects brainstem via cerebellar peduncles
-functions to smooth and coordinate the intended motion that is
happening detected by the proprioceptors
-functions in balance and coordination
-regulates tone and posture
, Diencephalon - Correct Answer - thalamus, hypothalamus, epithalamus,
CVOs
thalamus - Correct Answer - relays messages between lower brain
centers and cerebral cortex
- plays a role in maintaining consciousness
Hypothalamus - Correct Answer - maintains homeostasis
Epithalamus - Correct Answer - contains the pineal gland where
melatonin secretes
CVOs - Correct Answer - circumventricular organs - monitor chemical
changes because they lack a BBB
Cerebrum - Correct Answer - Largest part of the brain; responsible for
voluntary muscular activity, vision, speech, taste, hearing, thought, and
memory.
frontal lobe - Correct Answer - Responsible for consciousness and
communication, memory, attention, planning, personality, judgement,
voluntary movement (motor cortex)
parietal lobe - Correct Answer - portion of the cerebral cortex lying at the
top of the head and toward the rear; receives sensory input for touch
and body position
touch, pain, temp, and the sense of limb position
