Anatomy Of Brain Flashcards
Central sulcus
Divides the parietal from the frontal lobe
Where are the lobes
Frontal is superior, parietal is dorsal posterior, temporal is ventral, occipital is posterior
Parietal love
Taste, touch, smell, spatial and visual, math reading writing
Occipital
Visual
Frontal
Personality, problem solving, emotion, language,
Temporal
Hearing, learning, language, memory
Cerebellum
Coordination, balance
Brain stem
Unconscious tasks, reflexes
CNS
Brain and spinal chord
PNS
Branches out from CNS, autonomic and somatic
White matter
Fatty, myelinated axons
Grey matter
Non myelinated
Reticular matter
Dense Mix of grey and white, found in brain stem
Order of grey and white matter in brain and spinal chord
Brain- grey on out, white on in
Spinal chord- grey on in, white on out bc axons should be on out as their sending stuff out
How many main cerebral arteries are there
3, dorsal, ventral, medial
The claw
Meninges
Surround the CNS to hold it in place, three layers
Cerebrospinal fluid
Fills all the space in our CNS as a shock absorber and waste transporter
Three layers of the meninges
Dura mater - really tough outside
Arachnoid mater - spiderlike and connects dura to pia
Pia mater - tough inside that attaches to brain where blood brain barrier is
Blood brain barrier
Astroglia hold cells of blood vessels together in a mesh like barrier
Somatic nervous system
Voluntary skeletal muscles
Autonomic nervous system
Involuntary movement, sympathetic and parasympathetic
Sympathetic
Autonomic, stress, fight or flight reflexes, cortisol and adrenaline
Parasympathetic
Autonomic, rest and digest, calming hormones
What is between the arachnoid membrane and pia mater
The Subarachnoid space filled with CSF
