Chapter 4 Brain And Neurons Flashcards
Sulci vs gyre
Sulci are fissures or troughs
Gyre are the peaks
Brain and spinal chord are protected by
Cerebrospinal fluid, meninges and bones of skull and vertebrae
Fifth lobe of the brain
Insula deep within cerebral cortex, controls emotion
Appearance of cerebellum
Looks like tree branches
The medulla oblongata controls
Heart beat and rate
Rate and depth of breathing

Reflexes like sneezing and coughing
How many spinal and cranial nerves are there
31 spinal
12 cranial
PNS vs CNS
Peripheral everything that is not central ( The brain and spinal cord)
Motor vs sensory nervous systems
Motor is efferent, goes from CNS to effectors (skeletal muscles, organs)
Sensory is afferent goes from receptors to CNS
Somatic vs Visceral nervous systems
Parts of sensory nervous system
Somatic is skin and skeletal muscles
Visceral is internal organs
Autonomic vs somatic nervous systems
Conscious vs unconscious control
Parasympathetic vs sympathetic
Divisions of autonomic motor nervous system.
Rest and digest
Fight or flight
Acending and decending tracts
Parts of the spinal cord, go up or down

What triggers fight or flight
Anger, stress, fear, danger
Frontal lobe function
Problem solving, judgement, brochas area (speech, word formation)
