cerebrum and receptors

what is the cerebrum coorilated with

higher brain functions

what is the outer layer made of

grey matter

what is the inner layer made of

white matter

in general, each hemisphere controls 

the opposite side of the body 

longitudinal fissure

seperates cerebral hemispheres

corpus callosum

axons that connect the left and right hemisphere

gyrus

raised area/elevation of complex

sulcus

depression/groove between gyri

where does the frontal lobe end

central sulcus

what does the central sulcus do 

separates the frontal lobe from the parietal lobe  

what is the main functions of the frontal lobe

concentration, decision making

what is brocas area

the motor speech area, controls muscular movements needed for speech

where is broca’s area loacated

left frontal lobe

where is the primary motor cortex located 

located in precentral gyrus of each frontal lobe 

what is the function of the primary motor cortex

controls voluntary skeletal muscle movement

where does the parietal lobe end (lateral limits)

lateral sulcus

what is the lateral sulcus

groove that separates the frontal and parietal lobes from the temporal lobe

where is the primary somatosensory cortex located 

postcentral gyrus of each parietal lobe

what does the primary somatosensory cortex do

receives sensory input from skin, muscles and joints

where is wrenike’s area located

both in the parietal and temporal lobe

function of wernike’s area

helps us understand written/spoken language (speech comprehension)

where is the primary auditory cortex located 

temporal lobe 

where is the primary olfactory cortex located

in the temporal lobe

what does the primary auditory cortex do

receives and processes incoming sounds

what does the primary olfactory cortex do

processes smell information and provides conscious awareness of smells

where is the primary visual cortex 

occipital lobe 

what does the primary visual cortex do?

receives and processes incoming visual information

where is the insula located

deep to the lateral sulcus

functions of the insula

involved in processing taste information, and involved in memory

what is a receptor 

a structure that converts a sensory stimulus to a nerve impulse 

what are the three types of receptors (based on location)

exeroceptors, interoceptors, visceroceptors

where are exeroceptors located

near the surface of the body

examples of exeroceptors

cutaneous receptors, special senses (sight, smelling, taste, hearing, balance)

interoceptors (visceroceptors)

in the walls of organs 

examples of interoceptors

primary stretch receptors in smooth muscle viscera

what are proprioceptors

they provide information about the position and tension of muscles, joints, and tendons
