The term "higher brain centers" refers to those areas of the brain involved in higher-order functions. These centers would probably include nuclei, centers, and cortical areas of
cerebrum, cerebellum, diencephalon
Which of the following is the site of CSF production
The pons contains
tracts that link the cerebellum with the brain stem
The dural fold that divides the two cerebellar hemispheres is the
Cerebrospinal fluid is produced and secreated by
The primary purpose of the blood-brain barrier (BBB) is to
isolate neural tissue in the CNS from the general circulation
The centers in the pons that modify the activity of the respiratory rhythmicity centers in the medulla oblongata are the
apneustic and pneumotaxic centers
The final relay point for ascending sensory information that will be projected to the primary sensory cortex is the
The establishment of emotional states is a function of the
Coordination of learned movement patterns at the subconscious level is performed by
The two cereberal hemispheeres are functionally different, even though anatomically they appear the same
What are the three important function of the CSF
- 1) cushioning delicate neural structures
- 2) supporting the brain
- 3) transporting nutrients, chemical messengers and waste products
Which three areas in the brain are not isolated from the general circulation by the blood-brain barrier?
- 1) portions of the hypothalamus where the capillary endothelium is extremely permeable
- 2) capillaries in the pineal gland
- 3) capillaries at the coroid plexus
12 pairs of cranial nerves
- Olfactory Optic ocullomotor trochlear trigeminal abducens
- facial vestibulocochlear glossopharyngeal vagus accessory hypoglossal
Why can the brain respond to stimuli with greater versatility than the spinal cord?
The brain can respond with greater versatility because it includes many more interneurons, pathways, and connections than the tracts of the spinal cord
Breifly summarize the overall function of the cerebellum
Adjusts voluntary and involuntary motor activities based on sensory information and stored memories of previous experiences
The only cranial nerves that are attached to the cerebrum and the ______ nerves.
If symptoms characteristic of Parkinson disease appear, which part of the mesencephalon is inhibited from secreting a neurotransmitter? Which NT is it?
In parkinson disease, the substantia nigra is inhibited from secreting the NT, dopamine, at the basal nuclei
What varied roles does the hypothalamus play in the body?
- 1) subconscious ontrol skeletal muscle contractions
- 2) control of autonomic functions
- 3) coordination of nervous and endocrine systems
- 4) secretion of hormones
- 5) production of emotions and drives
- 6) coordination of autonomic and voluntary functions
- 7) regulation of body temperature
- 8) control of circadian rhythms
Stimulation of which part of the prain would produte sensations of hunger and thirst?
feeding and thirst centers of the hypothalamus
