Neurological System Flashcards
(20 cards)
Cerebrum
The general mass of the brain that is covered in a cerebral cortex. It is separated by the longitudinal fissure into a left and right hemisphere
Cerebral cortex
The outer surface of the brain; composed of gray matter. Contains the gyrus and sulcus
Fissure
A deep sulcus that identifies different brain regions
Longitudinal fissure
A deep fissure separating the brain into the left and right hemisphere
Hemisphere
One of two haves making up the cerebrum
Sulcus
A groove on the surface of the brain
Gyrus
Ridges of the cerebral cortex
Lateral sulcus
Separates the temporal lobe from other brain regions
Central sulcus
Separated the frontal and parietal lobe
Motor cortex
Primary motor functions of different body parts
Pre-frontal cortex
Include the Broca’s area and speech production
Olfactory cortex
Apart of the frontal lobe, sense of smell
Broca’s area
Speech production
Wernrickes area
Understanding of spoken language
Proprioception
Special awareness
Somatosensation
A general sensation throughout the body
Frontal lobe
The largest lobe in the brain; determines personality characteristics, logical reasoning, and decision making. Includes the olfactory cortex and broca’s area
Parietal lobe
Interprets touch and pain, as well as proprioception, and somatosensation. Includes the wernicke’s area.
Occipital lobe
Primary visual perception; Works with the parietal and temporal lobe to interpret visual information
Temporal lobe
Stores short term memories, musical rhythm, and helps with hearing.
