Transcript of AP Bio Nervous System

Nervous System
Hi, my name is Brian
I'm a little nervous...
Overview
Control center for your body
Receives and interprets information from the senses
Sends information to the muscles and glands
Two Parts
Central
Peripheral
Brain
bodies control center
Has 100 billion neurons
Spinal Cord
bundles of nerve fibers
connects the brain to the peripheral nervous system
Nerves
Connective Tissue
Peripheral
Somatic
Autonomic
Spina Bifida
Alzheimer's
Adrenoleukodystrophy
(ALD)
Causes
Mutation in gene that makes ALDP
Symptoms

muscle spasms
seizures
trouble swallowing
loss of hearing
trouble with language comprehension
impaired vision
hyperactivity
paralysis
coma
deterioration of fine motor control
crossed eyes
Treatments

taking Lorenzo’s oil to help lower elevated VLCFA levels
medications to relieve symptoms such as seizures
physical therapy to loosen muscles and reduce spasms
Causes
Symptoms
serious memory loss
confusion
any major change in the way the mind works
difficulty remembering newly learned information
Treatments
No cure
Many drugs to slow he worsening of symptoms and improve quality of life
Causes
Doctors are not certain


May be genetic or environmental
Symptoms
Mild Cases
no symptoms
dimple or birthmark on back

Severe Cases:
nerves protruding from back
spinal swelling
hydrocephalus
seizures
intellectual disability
sight problems
scoliosis
latex allergy
Treatments
surgery


brace or wheelchair


physical therapy
X- linked
adrenoleukodystrophy protein (ALDP) breaks down very long chain fatty acids
voluntary control of movement
involuntary control of movement
ex.
heart rate
digestion
respiratory rate
salivation
pupil dilation
perspiration
breathing
transmits impulses of sensation to the brain or spinal cord, and then to the muscles and organs.
protected by the spinal column, made of vertebrae
8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal
3 layers of spinal cord
dura mater, arachnoid mater, pia mater
Epineurium
Perineurium
Endoneurium
consciousness
goal setting
inhibition
attention
time perception
initiation of response of environment
judgement
control of emotional response
internalization of language
volition
memory for habits and motor activities
involved in everything, most commonly damaged in car accidents, matures until age of 25
expressive auditory
hearing ability, memory acquisition, categorization of objects, emotions, language
receptive auditory
increasing age
family history
visual input, visual perception, recognition of printed words
visual attention, touch perception, goal-oriented voluntary movements, use of multiple senses
Spinal Cord
Neuron
neurons
Nerve nets
ventral nerve cords
dorsal nerve cords
