nervous system Flashcards
Where is the primary somatosensory cortex
postcentral gyrus
What receives general sensory input from skin, joints, and tendons
Primary somatosensory cortex
The primary somatosensory cortex is capable of what?
Spatial discrimination, which is the identification of body region being stimulated
Where is the somatosensory association cortex located?
Posterior to the primary somatosensory cortex
What does the somatosensory association cortex do?
Integrates sensory input from primary somatosensory cortex for understanding of object. Determines size, texture, and relationship of parts of objects being felt
Where is the primary visual cortex
Extreme posterior tip of occipital lobe
Where does the primary visual cortex receive information from?
Receives visual information from retinas
Where is the visual association area and what does it do
surrounds primary visual cortex, uses past visual experiences to interpret visual stimuli (ability to recognize faces)
Where is the primary auditory cortex located and what does it do?
Superior margin of temporal lobes, interprets information from inner ear as pitch, loudness, and location
Where is the auditory association area located and what does it do?
Located posterior to the primary auditory cortex, it stores memories of sounds and permits perception of sound stimulus
Where is the primary olfactory cortex? And what is its purpose?
Located at the medial aspect of the temporal lobe, and it is the region of conscious awareness of odors
Where is the gustatory cortex and what does it do?
Located in the insula just deep to the temporal lobe. Involved in perception of taste
Where is the visceral sensory area and what does it do?
Posterior to the gustatory cortex, conscious perception of visceral sensations, ex. upset stomach or full bladder
What is cerebral white matter’s purpose?
Allows communication between cerebral areas and between the cortex and lower CNS
Cerebral White Matter: Association fibers
horizontal; connect different parts of the same hemisphere
