Lab Practical Flashcards
The mirror tracing task is a test of
implicit learning and memory
The order of the structures of the eye
cornea –> aqueous humor –> pupil –> lens –> ciliary muscles –> retina –>optic disc (blind spot) –> fovea
aqueous humor is between
cornea and iris/lens
vitreous humor is behind the
lens
the thin layer of tissue on the back of the eye that may appear as a clump of wrinkled gray tissue is the
retina
the shiny iridescent layer of tissue along the back inner surface of the eye is the
tapetum
The four corteces of the visual system
primary visual cortex
prestriate cortex
posterior parietal cortex
inferotemporal cortex
what does dorsal mean
top of the brain
another name for dorsal
superior
another name for ventral
superior
what does ventral mean
base of the brain
what does anterior mean
front of the brain
another name for anterior
rostral
what does posterior mean
back of the brain
another name for posterior
caudal
what does lateral mean
external side surface of the brain
what does medial mean
middle surface of the brain
The cranial nerve that functions with the sense of smell
olfactory
the cranial nerve whose function is visual
optic
The three cranial nerves whose functions are eye movements
oculomotor, trochlear, abducens
The cranial nerve whose sensory function is facial sensations and motor function is chewing
trigeminal
The cranial nerve whose sensory function is taste from anterior 2/3rds of the tongue and motor functions are facial expression, secretion of tears, salivation, and cranial blood vessel dilation
facial
The cranial nerve whose function is audition and receives sensory signals from the organs of balance in the ear
auditory-vestibular
The cranial nerve whoes sensory function is taste from posterior third of the tongue and the motor function of salivation and swallowing
glossopharyngeal
The cranial nerve whose sensory function is sensations from abdominal and thoracic organs and motor function is control over abdominal and thoracic organs and muscles of the throat
vagus
The cranial nerve whose motor function is the movement of neck, shoulders, and head and sensory function is that it receives sensory signals from muscles from the neck
spinal accessory
The cranial nerve whose motor function is tongue movements and whose sensory function is sensory signals from tongue muscles
hypoglossal
What is the sensory function of the olfactory cranial nerve
smell
What is the sensory function of the optic nerve
visual
What are the motor and sensory functions of he oculomotor, trochlear, and abducens cranial nerves
motor- eye movements
sensory- sensory signals from certain eye muscles
What are the sensory and motor functions of the trigeminal cranial nerve?
sensory- facial sensations
motor- chewing
What are the sensory and motor functions of the facial nerve
sensory- taste from anterior 2/3rds of the tongue
motor- facial expressions, secretion of tears, salivations, cranial blood vessel dilation
What is the sensory function of the auditory-vestibular cranial nerve
audition, and receives sensory signals from the organ of balance in the inner ear
What are the sensory and motor functions of the glossopharyngeal cranial nerve?
sensory- taste from posterior third of tongue
motor- salivation, swallowing
What are the sensory and motor functions of the vagus nerve?
sensory- senations from abdominal and thoracic organs
motor- control over abdominal and thoracic organs and muscles of the throat
What are the sensory and motor functions of the spinal accessory nerve
motor- movement of neck, shoulders, and head
sensory- sensory signals from muscles of the neck
What are the motor and sensory functions of the hypoglossal cranial nerve?
motor- tongue movements
sensory- sensory signals from tongue muscles
the most posterior division of the brain that is composed largely of tracts carrying signals between the rest of the brain and the body
medulla
the large, convoluted structure on the brain stem’s dorsal surface that is important in sensorimotor functioning
cerebellum
sulcus located towards the medial, posterior surface of the brain that is parallel to the longitudinal fissure
lateral sulcus
runs along the medial surface of the dorsal part of the brain
longitudinal fissure
brain structure that is found on the brain stem and creates a bulge
pons
