central nervous system Flashcards
central nervous system function: explain the main functions of the major divisions of the central nervous system, including spinal cord, brainstem, cerebellum, diencephalon, basal ganglia and cerebral hemispheres
function of central nervous system
communication and information processing: integrates, processes and coordinates sensory input and motor commands
functions of spinal cord
connects the PNS and ANS to brain, carries sensory signals to brain, carries motor signals to muscles, coordinates reflexes (e.g. patellar reflex)
functions of hypothalamus
integration hub which regulates temperature, hunger, thirst, hormone (connected with pituitary) and autonomic function
function of thalamus
integration centre for somatic and special senses information and projection to cortex; involved in emotional status, consciousness and appropriate motor response
function of basal ganglia
control of movement: fascilitating voluntary movement, inhibiting unwanted or inappropriate movements (fine tuning)
function of prefrontal cortex in frontal lobe
emotion, thinking, personality, judgement, planning
function of parietal lobe
primary sensory and association areas
functions of temporal lobe
hearing
function of motor association area
planning and sequence of movement created
function of Broca
motor programme for all muscles of speech
function of Wernicke
recognition of spoken and written language
function of limbic system
motivation, instinctive behaviour, emotion and memory
function of cerebellum
co-ordinates movement and is needed for learning motor skills
why is the cerebellum connected to the vestibular system
balance
why is the cerebellum connected to the spinal cord and muscles
locomotion, posture, muscle tone
