Muscles

Ability of muscle to shorten with force

Capacity of muscle to respond to a stimulus

Muscle can be stretched to its normal resting lengths and beyond to a limited degree

Ability of muscle to recoil to original resting length after stretched

Cardiac Skeletal Smooth

A connective tissue structure that surrounds muscles, groups of muscles, blood vessels, and nerves. It binds some structures together, while permitting others to slide smoothly over each other.

Where tendon forms attachment to muscle

Connection between tendon and bone

Layer of synovial membrane around the tendon which allows the tendon to stretch and not adhere to surrounding fascia

Energy system fatigue - no more ATP left so muscle can’t keep contracting Nervous system fatigue - nervous system unable to create impulses quickly enough to maintain stimulus and cause calcium to be released Voluntary nervous control - nerve telling muscle to contract stops sending the signal because the brain tells it to Involuntary nervous system control

Stretch receptors that detect length of muscle and speed of stretching and inform CNS

Nerve fibres between the tendon detect changes in muscle tension

Muscles are always slightly contracted due to spinal reflexes, keeps muscles firm, healthy and ready

Change in muscle length

Muscle shortens

Muscle lengthens

No change in muscle length

Muscle shortens at a consistent rate of speed
