pericardial cavity; visceral pericardium; parietal pericardium
|
|
what are the subdivisions of the abdominal cavitiy
|
peritoneal cavity; abdominoal cavity; pelvic cavity
|
|
what are the basic functions of the nervous system
|
monitors the internal and external environments; integrates sensory information; coordinates voluntary and involuntary responses of many organ systems
|
|
consists of brain and spinal cord; integrates and coordinates the processing of sensory data and the transmission of motor commands
|
(CNS) central nervous system
|
|
communication between the CNS and the rest of the body
|
(PNS) peripheral nervous systems
|
|
a cell in neural tissue specialized for intercellular communication
|
neuron
|
|
cells of the CNS that support and protect the neurons
|
neuroglia
|
|
areas in the CNS dominated by neuron bodies, glial cells, unmyelinated axons
|
grey matter
|
|
areas in the CNS that are dominated by myelinated axons
|
white matter
|
|
what is the structure of a neuron
|
dendrites,cell body, nucleus, axon, synaptic terminal
|
|
Bundle of axon that share a common origin,destination,function
|
Tracts
|
|
bundle of axons in the PNS
|
Nerves
|
|
collections of neuron cell bodies in the interior of the CNS
|
nuclei
|
|
collections of neuron cell bodies in the PNS
|
Ganglia
|
|
increase speed of action potential along the axon
|
myelin sheath( Schwann cells)
|
|
membrane potential of an undisturbed cell
|
resting membrane potential
|
|
explain how action potential are generated and propagated along a neuron
|
1) depolarization the threshold (Na+gate opens Na+ enters cell)
2) open sodium gates and rapid Repolarization( K+ gate opens K+ move out of cell) 3) Hyperpolarization( 3 Na+ into cell and 2 K+ out of cell ) 4) return to resting state |
|
action potential jumps from node to node
|
saltatory propagation
|
|
how doe's synaptic transmission accur
|
1) A.P. reaches the bulb
2) Calcium ions from (ECF) enters synaptic bulb and binds with visceral 3) this triggers Ach(neurotransmitter) to burst(lyse) 4)Ach travels to the receptors to postsynaptic membrane 5)AchE(enzyme) releases Ach from receptors |
|
process continues in a chain reactions that soon reaches the most distant portions of the axon
|
continuous propagation
|
|
how is information transferred to a neuron or to an effector?
|
neurotransmitters
|
|
major parts of the brain are
|
cerebrum, diencephalon, midbrain, pons, medulla oblongata, cerebellum
|
|
dura, arachnoid, pia mater give physical stability and shock absorption
|
meninges
|
|
acts as shock absorber and transports gases, nutrients chemical messengers and waste products
|
CSF (cerebralspinal fluid)
|
|
produce antidiuretic and oxytocin hormones
|
hypothalamus
|
|
releases 9 different homones
TSH,ACTH,FSH,LH,GH,MSH,PRL,ADH,oxytocin |
pituitary gland
|
|
has endocrine and exocrine cells, produces glucagin, secreate insulin regulates blood glucose levels
|
Pancreas
|
|
allow certain types of hormones to affect a target cell
|
receptors
|
|
maintains concentration of sodium and potassium and electrical charge of plasma membrane
|
sodium potassium pump
|
|
a electrical signal that affects the surface of the entire membrane
|
action membrane
|
|
movement of a membrane potential that moves it from a negative value toward 0mV
|
Depolarization
|
|
movement of a potential that moves it from +mV value to the resting potential
|
Repolarization
|
|
change, which may take a membrane potential from -70mV to -80mV
|
Hyperpolarization
|
|
rate at which action potential can be regenerated in an excitable membrane
|
Refactory period
|
|
a stimulus that either triggers a typical potential or not
