Anatomy Practicum Flashcards
Corpus Callosum
Relays infor between L and R hemispheres of cerebrum
Pinal Body
Produces melatonin. Regulates circadian rhythm
Thalamus
Relays sensory info to the cerebrum
Pyriform Lobe
Processes scent
Gray matter
regions of the brain unmyelinated neurons, neuronal cells
Spinal Cord
Carries information from brain to the body and vice versa
Pons
Sends signals to cerebellum and forebrain. Mediates sleep and arousal
Cerebrospinal Fluid
Protects brain and spinal cord, delivers nutrients to nervous tissue, removes waste products from cerebral metabolism
Cerebellar Vermis
Proprioception
Cerebellar Hemispheres
Motor Control
Temporal lobe
processing and perceiving sound, memory
medial longitude fissure
divides the cerebrum into the L and R hemispheres
Rhinal Fissure
divides the cerebrum from the underlying
Sylvian Fissure
Divides the frontal lobe from the temporal
Optic chiasm
part of the brain where the optic nerves partially cross
Olfactory Bulb
Nerve: 1 (I)
Function: processing oder
Optic
Nerve: 2 (II)
Function Transmit sensory info from the eye
Oculomotor
Nerve: 3 (III)
Function: Innervates muscles that move the eye, control eyelid elevation and pupillary constriction/accommodation
Trochlear
Nerve: 4 (IV)
Function: responsible for both lateral and vertical eye movement
Trigeminal
Nerve: 5 (V)
Function: Transmit info from face
Sensory: information from the skin, muscles, bone and teeth
Motor: biting, chewing, swallowing
Facial
Nerve: 7 (VII)
Function: Inneervates muscles of scalp and face. Taste.
Sensory: taste from the tongue
Motor: Facial expression, innervates salivary glands and tear glands
Vagus
Nerve: 10 (X)
Function: Innervates pharyngeal muscles, vocal cords, larynx, heart lungs, digestive organs. Sensory info from the viscera of abdomen and chest
Cerebellum
Fine motor control, motor coordination
Thalamus
Relays sensory info to cerebrum
Midbrain
Regulates eye movement and pupil dilation. Assists in motor control
