HUMAN A&P MUSCLES
Myosin myofilaments and the part of the actin myofilaments that overlap them- the dark band
A-band
Covers the entire muscle
Epimysium
Web like layer of connective tissue that surrounds a muscle and loosely connects it to other muscles
Fassica
A bundle of muscle fibers
Fassicle
acting filaments from adjacent sarcomeres and the z-disc they are anchored to the light band
I-band
Gap junctions found in cardiac muscle: help coordinate the heart beat
Intercalated disk
Ribbon like organelle found inside muscle fibers
Myofibrila
Actin or myosin containing structure
Myofilament
covers a muscle fascicle
Perimysium
contractile unit of muscle
Sacromere
Cell membrane of a muscle fiber
Sarcolemma
plasma membrane of the muscle cell
Sarcolemma
Cytioplasm of a muscle fiber
Sarcoplasm
Cord like extension of the epimysium connects muscle to bone
Tendon
A membrandous disj that is loacted between sarcomeres and the z-dsics as they are anchored to the light band
Z-disc
thin myofilament
actin
Covers an indivdual muscle fiber
endomysium
thin connective tissue investing each muscle cell
endomysium
Connective tissue ensheathing the entire muscle
epimysium
a discrete bundle of muscle cells
fascile
a muscle cell
fiber
A muscle cell
muscle fiber
indicates a word having to do with muscle
myo-/sacro-
actin and myosin make up the sarcomeres
myofilaments
A long filamentous organelle found withing muscle cells that has a banded appearance
myofirbril
Fat or thick myofilament
myosin
Connective tissue surrounding a fascicle
perimysium
contractile unit of muscle
sarcomere
Srripes or band on a muscle cell
striations
cordlike extension of connective tissue beyond the muscle, serving to attach it to the bone
tendon
