practical test Flashcards
function of axon
conduct electrical signals
function of dendrite
receive signals
the function of myelin sheet
protect axon, faster conduction
axon terminal function
connect another neuron of the effector. produce neurotransmitters, ACH, Dopamin, GABA
the function of the frontal lobe
It is responsible for the primary motor area, expression, language, conscious thoughts and problem-solving
the function of the Broca’s area
It regulates breathing and vocalization, the motor skills needed for speaking/ articulating
the function of the temporal lobe
primary auditory, smell and speech area.
consists of speech centre, Wernicke area
the function of the parietal lobe
Primary somatosensory and taste area. It processes sensory information
the function of the primary motor cortex
control movement
the function of the central sulcus
separates the frontal and parietal lobe
function of hypothalamus
regulate body temperature and control hormones
function of midbrain
relays visual and sensory signals
function of pons
links cerebellum with midbrain, diencephalon and cerebrum
function of medulla oblongata
contains reflex centres for regulating heartbeat, breathing and vasoconstriction. also contains reflex centres for vomiting, coughing
the function of cerebral ventricle
cerebrospinal fluid produced from choroid plexus
the function of occipital love visual cortex
optic nerve for vision
state the procedure which takes CSF for analysis
Lumbar puncture/spinal tap
function of CSF
cushion brain and spinal cord, transport nutrients, chemical and wastes
function of cerebellum
coordination and balance. control fine-tuned movements
the function of ventral root
carriers motor signals. if damaged, paralysis occurs
the function of spinal nerve
carriers motor, sensory autonomic signals between the body and spinal cord
the function of dorsal root
carriers sensory signals. if damaged, sensory loss
the function of central canal
CSF flowing inside. Site of intrathecal injection: spinal canal, subarachnoid space
function of the dura mater
protect the spinal cord, physical stability and absorb shock
the function of the subarachnoid space
spinal tap, intrathecal injection
what is the definition of afferent?
it Brings information to the CNS from receptors in
body tissues and organs. (sensory neuron)
what is the definition of efferent?
it carriers information away from the CNS to
effectors (muscles and glands that respond to
motor commands)
the function of vitreous
maintain pressure and helps retina in place
the function of the retina
receives focused light and converts to nerve signals
the function of the eye lens
changes shape to accommodate for focus
the function of the iris
control size of pupils
the function of the cornea
allow lights into the eyes
superior rectus is innervated by
oculomotor nerves. eyes lookup
lateral rectus is innervated by
abducens nerve
the function of the vitreous humor
maintain pressure and helps retina in place
the function of retina
receives focused light and converts to nerve signals
the function of eye lens
changes shape to accommodate for focus
the function of the cornea
allows light into the eyes
the function of the semicircular canals
maintains equilibrium and balance
the function of the auditory ossicles
amplify sound waves and connect the tympanic membrane to the inner ear
the function of the tympanic membrane
conducts sound waves to ossicles
the function of the vestibulocochlear nerve
hearing and balance
the function of the cochlea
consists of sensory receptors for hearing
the function of the auditory tube
equalizes the pressure in the middle year
