Types of joints
- fibrous
- cartilaginous
- synovail
-
Classificastions of mobility of joints, imobile to most mobile
- synarthrosis(immobile)
- amphiarthrosis
- diarthrosis(most mobile)
-
types of fibrous joints
- gomphoses
- suters
- syndesmoses
-
-
-
types of synovvial joints
- pivot
- hinge
- plane
- saddle
- ball and socket
- condylar
-
oraganization of muscle fiber big to small
- skelatal muscle
- fasicle
- muscle fibers
- myofibrils
- myofiliments
-
properties of muscles
- excitability
- contractibility
- elasticity
- extensibility
-
functions of muscles
- boby movement
- maintain posture
- tempeture
- storage and movement of materails
- support
-
muscle coverings outer to inner
- epimysium
- perimysium
- endomysium
-
sarcoplamic reticulum
store calcium
-
calcium binds to
troponin
-
sarcomere
z disc to z disc
-
repeating cycle of muscles
-
myosin head binds thick filements to actin in thin filiments is called what
crossbridging
-
nerve impulses are sent to
neuromuscular junction
-
isometric
muscle contracts but no movement or shortening
-
isotonic
movement occures, muscle tension is greater then resistance.
-
slow fibers
contract for long periods at a time, lots of mitichondrea
-
fast fibers
short burstes, larger in diameter, not very many mitichondrea
-
skeletal muscle organization
- circular
- parallel
- convergent
- pennate
-
afferent
inflowing trasmit to CNS
-
somatic sensory
- touch
- pain
- pressure
- volantary
-
viseral sensory
involuntary
-
cytoplasm of neuron
perikaryon
-
most sensory neurons are
unipolar
-
ofactory neurons are
bipolar
-
motor neurons that innervate muscle glands are
- multipolar the most common
- all motor neurons are multipolar
-
four types of glail cells of cns are
- astrocyte
- ependymal
- microglail
- oligodendrocyte
-
two types of pns glail cells are
- satellite
- neurolemmocytes
-
blood brain barrier
controls substances from entering the nervous tissues in the brain from the blood
-
saltatory conduction
nerve impulse jumps down mylonated sheath
-
countinuos conduction
is used in an unmylonated sheeth
-
wallerain degeneration
neurolemmocytes help repair a dammaged axon
-
cervical plexus
innervate anterior neck muscles as well as skin of the neck and portions of the head and shoulders
-
somatic motor(sns)
CNS to Skelatal muscles
-
autonomic motor(ANS)
- Viseral smooth
- smooth muscle
- cardiac
- Involunatary
-
heart wall srtucture outer to inner
- epicardium
- myocardium
- endocardium
-
conducting system of heart in order
- s node
- atroiventricular node
- atrionventricular bundle(bundle of his)
- interventricular septum
- perkinje fibers
-
the two cornary plexus
- sympathetic(t1-t5)
- parasympathetic(medulla oblongata)
-
sympathetic
speeds up the heart
-
parasympathetic
slows down heart
-
contraction of heart
systole
-
relaxation of heart
diastole
-
atria systole
- atrai contract
- av valves open
- semilunar closed
-
early ventricular systole
- atria relax
- ventricles begin to contract
- av valves forced closed
- semilunar valves closed
-
late ventricular systole
- atrai relax
- ventricles contract
- av valves remain closed
- semilunar valves open
-
early ventricular diastole
- atrai and ventricles relax
- av valvesremain closed and semilunar valves close
- atria fill with blood
-
late ventricular diastole
- atrai and ventricle relax
- atrai fill with blood
- av valves open ventricles fill
- semilunar closed
-
peristalisis(propulsion)
esphogaus
-
segmentaion(propulsion)
small intestine
-
tunic of the GI track inner to outer
- mucosa
- submucosa
- muscularis(forms the spingcters)
- serosa
