Draw a pic of a neuron -
…
where are cell bodies of sensory & motor neurons located -
sensory - take messages from the skin/organs to central nervous system
motor - take messages from the brain to muscles
at depolarization ……. in -
sodium
at repolarization …… out -
potassium
at refactoring ….. -
flip back
where are neurotransmitters made -
in the cell body of a neuron & transported down the axon and stores in vesicles
difference between myelinated and unmyelinated nerves -
myelinated - contain schwann cells that for from myelin sheaths
unmyelinated - lack myelin sheaths bc no schwann cells
Frontal Lobe -
- located in front
- controls abstract thinking
Pariteal Lobe -
- located behind frontal lobe in middle
- interprets sensory info to “feel”
Occipital Lobe -
- on the underside of the skull
- interprets vision
Temporal Lobe -
- located on sides by the temples
- interprets hearing and smell
Brain Stem -
- located before spinal cord
- consists of medulla, pons,midbrain
- allows the neurons travel through it to relay messages
Thalamus -
comes after midbrain
-the actual relay station
Hypothalamus -
exerts major control over nearly all body organs
Pineal Gland -
makes melatonin
Pituitary Gland -
produces hormones to regulate homeosatsis
Cerebellum -
helps maintain equilibrium, posture/coordination
which structure connects the hemispheres -
corupus callosum
the disorder of the brain is degenerative resulting in the destruction of neurons in the brain, genetics play a role, loss of memory and attention -
alzheimers
the disorder of the brain that is generally a stroke, it is the stopping of blood flow through the blood vessels of the cerebrum caused by a blockage -
cerebrovascular accident CVA
this brain disorder is a permanent, non-progressive damage to the motor control areas in the brain, caused by mostly prenatal conditions -
CP - cerebrall palsy
this brain disorder is where the degeneration of neurons results in a decreased amount of dopamine resulting in shaky hands and muscle weakness -
parkinsons
tough meninge containing many many tough fibers -
dura mater
is the cobby web looking meninge composed of elastic fibers and collagen-
arachnoid mater
