Unit 3

The subarachnoid space is filled with _______________. Blood plasma The blood brain barrier Progenitor cells Cerebrospinal fluid

Cross sections that resemble those of a salami and are perpendicular to the neuraxis are produced by a _______ section of the human brain. transverse horizontal sagittal parasagittal midsagittal

Tongue movements are controlled by the _____________ cranial nerve. Trigeminal Trochlear Hypoglossal Vagus

___________ come from the radial glial cells that are involved in the formation of new neurons. astrocytes. microglial cells. oligodendroglia. visual sensory neurons. progenitor cells.

Which of the following is FALSE of the evolution of the human brain? The size of primate brains have increased over the course of evolutionary history. Primate brain size increases depended on the creation of duplicate master genes. The human brain is smaller than that of any other primate. Comparisons of brain size within the primate family require an adjustment for body size. Activation of the ghrelin gene likely makes chimpanzee brains larger than human brains.

Which of the following is comprised of the pons and the cerebellum? metencephalon mesencephalon myelencephalon diencephalon telencephalon

Which of the following is correct regarding CSF? CSF carries nutrients to neurons. CSF is produced by the arachnoid granulations. The total brain volume of CSF is about 1250 ml. Drainage of CSF would result in compression of brain tissue onto the ventral skull surface. More than 12 hours is required to replace half of the CSF volume in a human brain.

What is a result of a stoppage of CSF flow? ischemic stroke myasthenia gravis anencephalus Parkinson's disease hydrocephalus

Which of the following most accurately describes the general functions performed by the left and right hemispheres? The two hemispheres perform identical functions.

The right hemisphere is adept at the serial analysis of information.

The primary auditory cortex can be found in the _______ lobe insular parietal frontal temporal occipital

In which sensory system does sensory information from the left side of the body travel to the ipsilateral hemisphere? somatosensation audition vision olfaction pain

Damage to the amygdala would be expected to alter emotion. planning of motor behavior. language acquisition. hearing of loud sounds. long-term memory.

An anesthetic drug injected near the dura around the cauda equina would deaden pain sensation in the pelvic region. neck and upper chest. fingers. tongue. forehead.

The midbrain is comprised of the pons and medulla. dorsal horn and ventral horn. thalamus and hypothalamus. superior colliculus and inferior colliculus. tectum and tegmentum.

Which structure is involved specifically with emotions? Amygdala Basal ganglia Pituitary gland Hippocampus

Which of the following belong together? oxytocin; stimulation of milk ejection from the breast vasopressin; induction of uterine contractions during childbirth vasopressin; overeating vasopressin; release of ACTH from the posterior pituitary oxytocin; regulation of urine output

The layers of meninges from outermost to innermost are: Dura mater, subarachnoid space, arachnoid membrane Pia mater, arachnoid membrane, dura mater Dura mater, arachnoid membrane, pia mater Pia mater, dura mater, subarachnoid space

The brain floats within ________ fluid, which is contained within the ________ . cerebrospinal; subarachnoid space extracellular; dura mater interstitial; subarachnoid space intracellular; pia mater cerebrospinal; blood vessels

The anterior end of the neural tube will eventually form 3 interconnected channels called the myelencephalon. ventricles. telencephalon. mesencephalon. cerebral cortex.

In brain development, the period of asymmetrical division lasts about ___ months. 6 3 9 2

The human brain starts to resemble a _____________ by the 28th day of embryonic development. hollow tube series of ridges round balloon shallow plate series of increasingly larger rectangles

You have just become a neurologist. (Congratulations!) Your first patient is partially paralyzed on the left side of his body. You might suspect that he has suffered damage to what area of the cerebral cortex? the left parietal lobe the left frontal lobe the right frontal lobe the right temporal lobe the right parietal lobe

The limbic system is part of which major division of the brain? Mesencephalon Forebrain Hindbrain Diencephalon

Which brain region is NOT part of the limbic system? fornix amygdala putamen part of the cortex hippocampus

Perceiving, learning, planning and acting take place in the _____________ of the cerebral cortex. Association areas Primary somatosensory areas Occipital area Motor areas

Postganglionic sympathetic fibers secrete the neurotransmitter _________, while preganglionic sympathetic fibers secrete _________. acetylcholine; norepinephrine glutamate; acetylcholine acetylcholine; acetylcholine norepinephrine; acetylcholine serotonin; norepinephrine

A _______ is a bulge of tissue located between grooves in the cortical surface of a human brain fissure ventricle foramen sulcus gyrus

Which of the following is a subcortical structure? dura mater parietal cortex hypothalamus broca's area spinal cord

The _______ lobe houses the primary somatosensory cortex. frontal temporal insular occipital parietal

The _________________ of the _________________ is responsible for slowing of heartbeat. Sacral nerves; sympathetic nervous system Efferent spinal nerves; parasympathetic nervous system Cranial nerves; parasympathetic nervous system Afferent spinal nerves; parasympathetic nervous system
