Practical 3: Neuroanatomy Flashcards
what is the most noticeable feature of the mammalian brain
the cerebral cortical hemispheres, ie enlarged cortex
what the gyri and sulci
folds in the cerebral cortex due to raised areas (gyri) that are separated by dips (sulci or fissures)
what is the longitudinal fissure
the deep groove that separates left and right hemispheres of the brain
describe the structure of the cerebellum
cauliflower structure
what is the function of the gyri and sulci
they are folds of the brain which increase surface area
what is the function of the frontal lobe
somatosensory (touch) area
what is the function of the parietal lobe
primary motor control area
what is the function of the occipital lobe
primary visual sight area
what is the function of the temporal lobe
primary auditory sound area
what are the four cortical lobes of the brain
frontal parietal occipital and temporal
the frontal lobe processes which three of the following types of information
cognitive reasoning
language production
emotion
the temporal lobe processes which three of the following types of information
primary olfactory smell area
language comprehension
memory
the central sulcus separates which lobes
the frontal lobe and parietal lobe
the lateral fissure separates which lobes
the frontal and parietal lobes
what gland sits under the hypothalamus and serves as the brains link to the hypothalamus
the pituitary gland
draw the sympathetic chain and spinal nerve in relation to the spinal cord
sympathetic chain running parallel close to the spinal cord and spinal nerve is further away from the spinal cord and sympathetic chain, runs perpendicular to sympathetic chain
what is the conus terminalis
the tapered lower end of the spinal cord
the spinal cord is part of which nervous system
the central nervous system
the spinal nerves are part of which nervous system
peripheral nervous system
the sympathetic chain forms part of which nervous system
the autonomic nervous syste
draw the five regions of cortex
frontal then parietal then occipital as the top three regions of cortex, with the temporal beneath the three and then the cerebellum under the temporal and occupital
what are the three divisions of the brainstem from top to bottom
midbrain
pons
medulla
(spinal cord)
what is more accurate a light microscope of a dissecting scope and why
the light microscope because we were able to get a higher degree of magnification
the dorsal root contains what neurons
sensory
