Parts of the Brain Flashcards
Cerebrum
Two hemispheres split by the longitudinal cerebral fissure; connected by corpus callosum
5 lobes of the cerebrum
Occipital lobe
Frontal lobe
Parietal lobe
Temporal lobe
Insula lobe
Gyri, precentral gyrus, postcentral gyrus
Folds for surface area
Sulci, central sulcus
Grooves for surface area
Cerebrum
Two hemispheres, divided into five lobes
Responsible for higher mental function such as learning, memory, personality, cognition, language and conscience
Diencephalon
Responsible for processing, integrating, and relaying information to different parts of brain
Cerebellum
Posterior and inferior portion of brain
Involved in planning and coordination of movement especially complex activities such as playing sport or instrument
Brainstem
Connects brain to spinal cord
Involved in basic involuntary homeostatic functions, control of certain reflexes and monitoring movement.
Grey and white matter
Grey- outer part of cerebrum
White- deep in brain
Meninges
Dura mater- outer most layer
Arachnoid mater- transparent, middle layer
Pia mater- delicate, inner layer
Frontal lobes
Neurons responsible in planning and executing movement such as behavior, conscience, and personality. Cognition, speech and motor control
frontal bone to central sulcus
Parietal lobes
Neurons are responsible for processing and integrating sensory information and function in attention. Taste.
Central sulcus to parieto-occipital sulcus
Temporal lobes
Temporal bone to lateral sulcus
Neurons in these lobes are involved in hearing, language, memory, and emotions.
Occipital lobes
From parieto-occipital sulcus to occipital bone
Principal visual center
Insula
Deep to lateral sulcus
Taste, visceral sensation, and language. Hearing
Motor areas
Located in frontal lobe
contains upper motor neurons which are interneurons.
Primary motor cortex, involved in conscious, planning of movement. Precentral gyrus of frontal lobe
