Cerebrum (Cerebral Cortex)
Outermost layer (and largest part) of the brain; responsible for thinking and processing information from the five senses
"Little brain" located below and behind the cerebrum; controls balance and coordination
Part of the forebrain, below the corpus callosum; relay station for sensory information
Small area above the pituitary gland and below the thalamus; controls hunger, thirst, and temperature
The large band of neural fibers connecting the two brain hemispheres and carrying messages between them.
Controls the left side of the body; it is the more artistic and creative side of the brain
Controls the right side of the body; it is the more academic and logical side of the brain
Frontal and upper area of the cortex; responsible for thinking, decision making, and planning
Upper, back part of the cortex: Processes taste, temperature, and touch
Bottom middle part of cortex, right behind the temples; processes auditory information (hearing)
Bottom, back part of the cortex; processing visual information (sight)
shallow groove int he brain
ridge on the brain
The portions of the central nervous system that are abundant in cell bodies of neurons rather than axons. Unmyelinated.
Whitish nervous tissue of the CNS consisting of neurons and their myelin sheaths.
Almost all gray matter , located between the midbrain and the cerebrum and consists of the thalamus, hypothalamus, and pineal body
Integrates sensory and motor commands
structure that connects the brain and spinal cord; includes the medulla oblongata and the pons
A brain structure that relays information from the brain to the cerebellum
Function of Pons
Regulates respiration, swallowing, facial muscle movements
A brain structure located near the thalamus that secretes melatonin.
Part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion.
thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord
Delicate, weblike middle layer of the meninges.
Inner layer of meninges; intimately attached to brain following contours; carries small blood vessels to nourish underlying nervous tissue;
Fluid in the space between the meninges and within the ventricles that acts as a shock absorber which protects the central nervous system.
The brain contains four fluid-filled spaces called the:
a collection of blood in the space between the skull and dura mater
inflammation of the brain
Inflammation of the meninges
an irreversible, progressive brain disorder, characterized by the deterioration of memory, language, and eventually, physical functioning
Incurable disease affecting adults which is a spongiform encephalopathy caused by a prion ; is fatal usually within 1 year of onset; results in cortical and cerebellar atrophy; and is characterized by a rapidly progressive dementia with myoclonus (sporadic, jerky muscle movements)
Autoimmune disorder that attacks the proteins in the myelin sheath causing a short circuit of the nervous system resulting in person being unable to control muscle movement.
Sudden loss of consciousness, sensation, and voluntary motion caused by rupture or obstruction (as by a clot) of a blood vessel of the brain.
