Exam 4 Flashcards
Which ventricle is found under the corpus callosum
Lateral ventricle
What passageway connects the third and fourth ventricles
Cerebral aqueduct
What passageway is found in the spinal cord and ventricles
Central canal
True or false? Cerebrospinal fluid is produced within the ventricles
True
Are the ventricles all interconnected? True or false
True. Narrow passageways content them together
What area takes visual info from one side of the body to the other?
Optic chaism
What gland can be found on ventral surface of brain
Pituitary gland
The _________ attaches the pituitary gland to the Brain
Infundibulum
What structure connects the right and left cerebral hemispheres
Corpus callosum
The third ventricle drains into the fourth via
What brain nucleus serves as the body’s master clock
Suprachiasmatic nucleus
And elevated ridge on the surface of cerebrum is called the
Gyrus
2 brain structures directly associated with maint. Of homeostasis include
Certain nuclei in the brain stem and hypothalamus
During development of nervous system, telencephalon becomes
Cerebral hemispheres
Where is the primary visual cortex located
Occipital lobe
All stimuli destined for the cerebral cortex first must pass thru
The thalamus
What is not apart of the cerebrum
Brainstem
What provides a link between nervous and endocrine system
Hypothalamus
What gland of diencephalon secretes the hormone melatonin
Pineal gland
Cerebella cortex is folded looking like trees of white matter, what are the trees called
Arbor vitae
What regulates homeostasis, ANS, endocrine system, and the sleep/wake cycle
Hypothalamus
What are the 3 primary vesicles that form the neural tube
Forebrain midbrain hindbrain
What is the most important part of our brain for survival
Brainstem
In the brain, the ability to produce language is the function of
Broca’s area
The ability to UNDERSTAND language is the function of
Wernickis area
The neurotransmitter orexin’s role is
Promotion of wakefulness
The tracts of anterolateral system decussate in the
Posterior horn
The tracts of posterior columns decussate in the
Medulla
The difference between the intended movement and the actual movement that is taking place is regulated by
The cerebellum
_ Is not carried out by anterolateral system
Discriminative touch
Someone who has difficulty in continuing a movement regularly has damage to the
Cerebellum
______ is not a mechanical sense
Temperature
Where are lower motor neurons cell bodies located
Anterior horn of gray matter
The________ special sense does not travel through the thalamus at all
Olfaction
In what area do second-order neurons will synapse with third-order neurons
The thalamus
The thalamus serves as a direct gateway into cerebral cortex for these special sensory stimuli
Hearing, vision, and taste
What part of the brain modifies the activity of upper motor neurons, to produce vol. Movement and inhibit invol. Movements
Basal nuclei
Where do the fibers off the corticospinal tracts decussate
Medulla
Where 1s the first sensation of touch processed
Primary somatosensory cortex (s 1)
Where are cell bodies of lower motor neurons located
Anterior horn of spinal gray matter
What body region has the most sensory receptors, there for, has more space dedicated to them in the primary somatosensory cortex
Lips / tongue
What info is received by the primary vestibular cortex
Equilibrium
Motor areas of the cerebral cortex, basal nuclei the cerebellum and the spinal cord
Planning and coordinating voluntary movement
A critical function of the basal nuclei is to
Inhibit inappropriate movement
What somatic motor neuron innovates the lateral rictus muscle
Abducens(VI)
Sympathetic nervous system and parasympathetic nervous system are divisions of
Visceral motor division( ans)
