The Brain and Cranial Nerves
What are the 4 major parts of the brain ?
- diencephalon, brainstem, mid brain, thalamus
- cerebrum, cerebellum, diencephalon, pons
- cerebrum , cerebellum, diencephalon, brain stem
- thalamus, diecephalon, pons, mid brain
- none of the above
What are the primary brain vesicles?
- Prosencephalon, myelencephalon,metencephalon
- Prosencephalon, mesencephalon, rhombencephalon
- Prosencephalon, diencephalon, rhombencephalon
- none of these
- all of these
The brain and spinal cord develop from the:
- The Ectodermal Neural Tube
- The Mesodermal Neural Tube
- The Endothelial Neural Tube
- The Epithelial Neural Tube
- Lamina Porpria
The cerebral hemispheres are connected internally by a broad band of white matter known as the:
- White commissure
- Corpus callosum
- Dura mater
- Central canal
The brain stem consists of the:
- medulla oblongata, pons, and diencephalon.
- midbrain, diencephalon, hypothalamus
- medulla oblongata, pyramids,epithalamus
- none of these
- all of these
Which of the following is not a function of the thalamus?
- Relaying information from the cerebellum and basal nuclei to primary motor areas of the cerebral cortex
- Helping maintain consciousness
- Playing a role in emotions and memory
- Regulating body temperature
- Relaying sensory impulses to the cerebral cortex
In which of the following ways does cerebrospinal fluid contribute to homeostasis?
- Mechanical protection, chemical protection, Immuntiy
- Chemical protection, electrical protection,circulation
- Electrical protection
- mechanical protection, circulation
Which of the following statements is false?
- Association tracts transmit nerve impulses between gyri in the same hemisphere.
- Commissural tracts transmit impulses from the gyri in one cerebral hemisphere to the corresponding gyri in the other hemisphere.
- Projection tracts form descending and ascending tracts that transmit impulses from the cerebrum and other parts of the brain to the spinal cord, or from the spinal cord to the brain.
- The internal capsule is an example of a commissural tract.
- The corpus callosum is an example of a commissural tract.
Which of the following statements is true?
- The right and left hemispheres of the cerebrum are completely symmetrical.
- The left hemisphere controls the left side of the body.
- The right hemisphere is more important for spoken and written language.
- The left hemisphere is more important for musical and artistic awareness.
- Hemispheric lateralization is more pronounced in males than in females.
The mixed cranial nerve that contains sensory neurons from the anterior 2/3 of the tongue and motor neurons that innervate neck muscles is:
- Cranial nerve IX; the glossopharyngeal nerve
- Cranial nerve V; the trigeminal nerve
- Cranial nerve XII; the hypoglossal nerve
- Cranial nerve VII; the facial nerve
Decussation of the pyramids is the reason that each half of the cerebral cortex controls the opposite half of the body, and this takes place in the:
- Medulla oblongata
- Cerebral cortex
Nerve impulses relaying motor information from the cerebrum to the spinal cord would pass through the:
- Cerebral peduncles in the cerebellum
- Arbor vitae in the midbrain
- Cerebral peduncles in the midbrain
- Arbor vitae in the cerebellum
