Pilates Anatomy U2 Muscular System
Characteristics of Skeletal Muscle Tissue - ANSVoluntary movement
Produces skeletal movement
visible striations
multiple nuclei
Characteristics of Cardiac Muscle - ANSfound only in the heart, striated, involuntary control,
single nucleus, moderate rate of contraction, no regeneration capability
smooth muscle characteristics - ANSno striations
spindle-shaped cells
single nucleus
involuntary
found in walls of hollow organs. Found in digestive tract
Muscle Tissue Organization (small to large) - ANSMyofilaments
Myofibrils
Muscle Cells
endomysium
fascicle
perimysium
whole muscle
epimysium
Muscle Tone - ANSsmall amount of contraction that is always on muscle to keep our posture
and keep it ready to contract
Recruitment - ANSphenomenon where the body adds additional motor units to move when
those activated are not enough
Tetanus - ANSfull contraction of muscle without relaxation (also a disease where this occurs,
nicknamed lockjaw)
Origin - ANSpoint of attachment of a muscle to a stationary bone or tissue
Insertion - ANSattachment point of a muscle that is being moved by its contraction
Action - ANSmotion perpetuated by a muscle contraction
anaerobic respiration - ANSmetabolic process by which ATP is made in the absence of oxygen
