between the origin and insertion Origin
which is usually located proximally in
limbs ?
What happens during REVERSE specific movements of the body the actions are
MUSCLE ACTION? reversed THEREFOR the positions of the origin and
insertion of a muscle are switched
What is a mechanical advantage if the load is closer to the fulcrum and the effort
using the example of a lever? is farther from the fulcrum only a small about of
effort is needed to move the load
Bones serve as levers and fulcrum
joints serve as for the lever
Agonist (Prime Movers) _________ muscles contract, relax
while antagonist ____________ muscles
What are muscles that contract and synergists
stabilize the intermediate joints
called?
What is a group of skeletal muscles, Compartment
their blood vessels, and nerves
called?
,Origin an insertion of the masseter Origin = maxilla and zygomatic arch
Insertion = angle and ramus of the mandible
What is the origin of the deltoid ? acromial extremity of clavicle, acromion, and spine
of scapula
What are the 3 muscles that make up semimebranosous, semitendinosus, biceps femoris
the hamstring ?
What 4 muscles make up the Quads rectus femoris, vastus lateralis, vastus medialis,
? vastus intermedialis
What do you call a small mass of Ganglia
nervous tissue that is made up
primarily of neuron cell bodies?
The somatic nervous system skeletal
only sends impulses to
_______________________
muscles
Fight or Flight is associated Sympathetic
with which division of the
autonomic nervous system?
What is the ability to respond to a electrical excitability
stimulus and convert it into an action
potential?
, What type of neurons usually have Multipolar
several dendrite and on axon , and
are norm ally found in brain and
spinal cord as well as motor
neurons?
What type of neurons have one main Bipolar
dendrite and one axon as well as are
primarily found in the retina of the
eye, inner ear, and the olfactory area
of brain?
What type of neurons has Unipolar or Pseudounipolar
dendrites and one axon that are
fused together to form a continuous
process that emerges from the
cell body?
The processes of_______make contact astrocytes
with blood capillaries, neurons, and
the pia mater
What neuroglia has these functions? Astrocytes
1. contain microfilaments that
give them strength and allow
them to support neurons
2. contributes to the effectiveness
of BBB
3. in embyro, they secret
chemicals that regulate things
4. help maintain an appropriate
chemical environment for
nerve impulse generation
5.play a role in hearing and memory
