control and coordination Flashcards
human nervous system
cns
pns
cns
brain
spinal cord
pns
spinal nerve-connected to spine
cranial nerve- c to brain
visceral nerve
neuron
structural and functinal unit of nervoous system
parts of neuron
dendrite-recieve info from other neuron
cell body- convert to electrical impulse
axon-transmit it to next neuron
synapse-gap between two neuron
types of neuron
sensory-receptor to cns
motor-cns to effector(muscle)
interneuron-connnect both
brain
protected by cranium
surrounded by 3 membrane-meninges
filled with cerebera spinal fluid
3 region of brain
forebrain
midbrain
hindbrain
forebrain
1]cerebrum(largest)
|
frontal lobe-memory,speak
temporal-smell
parietal-pain
ocipital-visual
2]hypothalemus-contral sleep cycle
3]thalamus-connect them
spinal cord
31 pair of nerves
enclosed in bony case calledd vertebral coluumn
hind brain
cerebullum-control postuere and balance and voluntary activities
medulla-involuntary action
pons-regulate respiration
types of glands
excrine-do not secrete hormone
endocrine- secretes
actions
voluntary
inv—–
reflex-controllled by spinal cord
pituitary gland
growth hormone
thyroid gland
throxine(contain iodine)
control metaboolism,fat and protein
parathyroid galnd
parathormone
regulate calcium and phosphate level
thymus gland
development of immuen system
shrinks after puberty
pancreas
exo-pancreatic juice
endo-insulin and glycogen
adrenal
regulate heart rate
galnd of emergency
testes
testestorone
movement in pant
nastic-not related to growth
trophic-related to
types of tropism
positive
negative
What is the area of contact between the neuron and the muscle cell called
Neuromuscular junction
Which of the following hormones are responsible for such changes during puberty
testesterone
oestrogen
