Muscle tissue
There are three types of muscle tissue
cardiac
cardiac muscle is only found in the heart and is an extremely specialized form of muscle tissue that has evolved to pump blood throughout the body
cells are long and have a single central nucleus
smooth
smooth muscle are fibers that are located in walls of hollow visceral organs
cellls are spindle shaped with single central nucleus
skeletal
Skeletal muscle is found between bones and it is used to effect skeletal movement such as locomotion and to maintain posture.
skeletal celles are long, cylindrical parallel and multinucleated
major functions
Movement
When muscles contract, they contribute to gross and fine movement.
posture
Skeletal muscles help keep the body in the correct position when someone is sitting or standing.
stability
Muscle tendons stretch over joints and contribute to joint stability
Circulation
The heart is a muscle that pumps blood throughout the body.
urination
The urinary system comprises both smooth and skeletal muscles
extension
movement that increases angles of joints
flexion
movement that decreases angle of joints
opposition
movement of thumb
inversion
turn of sole medially
physiology of muscle contraction
isotonic contraction
muscle changes length, causing the insertion end
Body movment such as walking and running
muscle that produces movement of joint
Isometric
Tension within the muscle increase
Muscle does not shorten
Contraction that do not produce movement
Twitch and tetanic contraction
Laboratory phenomena and do not play a role
single contraction of muscle fibers caused by single threshold
Steady contraction caused by serious stimuli
