36 terms · These are flash cards for Anatomy and Physiology focusing on the anatomy of muscles

Endomysium

The innermost connective tissue covering muscle cells

Fasciles

Groups of fibers.

Perinysium

The layer in the middle of connective tissues in the muscles.

Epimysium

Entire muscle sheath.

Insertion

The point where the muscle attaches to the bone/bones that don't move.

Prime mover

This is the muscle type that does the movement.

Antagonist

This is the muscle type that opposes the movement of the prime mover.

Synergist

This is the muscle type that helps the prime mover move the muscle most efficiently.

Fixator

This muscle type focuses on keeping the joints stable.

Aponeurosis

Extensions of the epimysium that connect to adjacent muscle.

First Class Lever

Fulcrum is in the middle between the weight and the force.

Second Class Lever

Fulcrum is on one end. Weight is in between fulcrum and upward/downward force.

Third Class Lever

Fulcrum is at the end, however upward/downward force is between the weight and the fulcrum. Most common lever in the body.

Central Nervous System

Brain, Spinal cord

Peripheral Nervous System

Nerves in the perephry of the body, spinal nerves and cranial nerves.

Afferent Nervous System

incoming sensory pathways

Efferent Nervous System

Out going motor pathways

Somatic Nervous System

Voluntary control muscles

Autonomic Nervous System

Carry involuntary signials

Sympathetic division

flight of fight response

Parasympathetic division

Coordinating normal resting activities

Neuroglia

Support cells, remain capable of cell division

Astyocytes

Form tight sheath around brain's blood capalaries. make up "Blood-brain barrier"

Microglia

Small, usually stationary, cells involved in phagocytosis

Eperdymal cells

from thin sheets that the fluid-filled cavities in the brain

oligoclendrocytes

produce myelin sheaths in PNS

Schwann cells

produce myelin sheaths in PNS

Nerve fiber

nerve cell which is composed of dendrites and axon

Dendrite

Receive stimuli

Axon

carry stimuli away

interneurons

spinal cord nerves

Endoneurium

Innermost layer of protective tissue for a nerve cell

Perineurium

Middle layer of protective tissue for a nerve cell

Epineurium

Outermost layer of the protective shell for nerve cells

White matter

myelinated fiber

Grey matter

unmyelinated fiber
