Terms in this set (33)
the outer meningeal layer that lies closest to the bone
the middle meningeal layer
meningeal layer that lies directly over the brain
the most superior part of the brain, split into large paired masses
part of the brain directly above the brain stem and under the cerebrum. Made up of the thalamus and hypothalamus
the most inferior part of the brain, it is the "stalk" of the brain that reaches down to meet the spinal cord. It is composed of the medulla oblongata, pons, and midbrain
large portion of the brain posterior to the brain stem and inferior to the cerebrum. It is responsible for equilibrium, motor coordination, and memory of learned motor skills.
responsible for voluntary motor functions, motivation, foresight, planning memory, mood, emotions, social judgement, and aggression (basically the higher brain functions)
receives and interprets general senses for taste and some visual processing
primary visual center of the brain
hearing, smell, learning, memory, and some vision
not well understood but thought to play a role in understanding language, with less major roles in taste and integrating visual senses.
the right and left halves of the cerebrum
deep midsaggital fissure that splits the cerebrum into right and left hemispheres
a bulging fold in the cortex of the cerebrum or cerebellum
small grooves between the gyrus
tract of white matter connecting the two hemispheres of the cerebrum
shaped like a barbell with two oval masses on each end connected by a skinnier intermediate mass. It is the largest part of the diencephalon and lies immediately inferior to the corpus callosum. Acts as a point of information relay for nearly all signals (not olfactory) passing from the lower CNS to cerebrum.
lying just below the thalamus, it is the inferior portion of the diencephalon and controls many fundamental physiological functions such as appetite, thirst, and body temp and exerts effects through the endocrine and autonomic nervous system.
small body just posterior to the hypothalamus, involved in the process of recognition memory and believed to add the sense of smell to memory
small piece of tissue off the bottom of the brain from which the pituitary gland hangs. Just below the hypothalamus
just posterior to the thalamus and beneath the corpus callosum this gland secretes melatonin which helps regulate day/night cycles.
similar to the cerebrum the cerebellum is split into right and left hemispheres
narrow strip of tissue separating the two hemispheres
the highly branched white matter seen in a midsaggital section of the cerebellum. Conducts sensory and motor information to and from the cerebellum
the most inferior part of the brain stem this is a swelling just above the spinal cord. It functions as a relay station to the brain with all nerve fibers connecting the brain to the spinal cord passing through here
broad anterior bulge above the medulla oblongata. The pons is dominated by tracts of white matter and it acts as a relay station to direct sensory information to the thalamus and cerebellum
the most superior part of the brain stem, the mid brain lays directly inferoposteriorly to the thalamus
connected by the infundibulum it hangs down just under the hypothalamus. COnsidered to be a "master gland" it is an endocrine gland which secretes hormones controlling homeostasis
just posterior to the pineal gland this body contains the superior colliculus (visual reflexes) and the inferior colliculus (auditory reflexes)
large fissure between the cerebellum and cerebrum
just inferior and anterior to the hypothalamus this is a small bulb where the optic nerves partially cross
small bulbs on the bottom of the front of the brain, they are centers for olfactory senses (smell)
