The brain : week three Flashcards
protecting the CNS
the skull and the spine
brain regions
- forebrain
- midbrain
- hindbrain
- reticular formation
- cerebral cortex
- spinal cord
hindbrain regions
pons
medulla
cerebellum
what does the pons do
- relays information between brain areas
- communication between lungs and the trachea
what does the medulla do
- regulates autonomic functions
- helps sympathetic and parasympathetic systems
what does the cerebellum do
- skeletal muscle movement/coordination
- balance
where is the hindbrain
at the base of the brain
where is the midbrain
part of the brain stem in the centre of the brain
midbrain functions
- processes sensory information
- regulates sleep and physiological arousal
- involved in motor movement
- hormone production
what is the reticular formation
a net like structure of neurons along the brain stem
forebrain components
the cerebrum, thalamus and hypothalamus
what is the cerebrum responsible for
a range of sophisticated functions
what does the thalamus do
- filters sensory/motor signals
- regulates attention, arousal and activity
what is the hypothalamus responsible for
homeostatic functioning
motivated and emotional behaviours
hemispheres of the brain
left and right
what is the skull
solid bone that protects the brain
how many bones does the skull have
22
what is the spine
vertebrae that protects the spinal cord
where is the forebrain
located at the top and front of the brain
(largest lobe)
what does contralateral mean
one side of the brain controls the opposite side of the body
what is the cerebrum divided into
left and right hemispheres
what is hemispheric specialisation
each side of the brain has its own special functions
what does the reticular formation do
connects various parts of the brain and spinal cord
