Question | Answer |
4 muslce tissue Properties | Excitability Extensibility Contractility Elasticity *All of these properties allow a muscle to produce forcer over and over |
Excitability (Irritability) | Sensitivity to chemical, electrical, or mechanical stimuli |
Contractility | Ability to Contract and develop Tension or Internal F against resistance when stimulated |
Extensibility | Ability to be passively stretched beyond its normal resting length. |
Elasticity | Ability of muscle to return to its original length following stretching |
Intrinsic | Ex- Brachialis Contained wholly within the organ on which it acts Origin and Insertion are contained within the two body parts |
Extrinsic | Ex-Biceps Brachii Muscle originates outside of body part upon which it acts Origin and insertion are not necessarily in btwn the two bones it's acting on |
Action | Ex- Biceps Brachii has the action of flexion at elbow Specific mvmnt of joint resulting from concentric contraction Usually cause by a group of muscles working together *A muscle may cause more thatn one action at the same join or at a different joing |
Innervation | segment of the nervous system responsible for providing stimulus to muscle fibers within specific portion of muscle *A muscle may be innervated by more than one nerve and one nerve may innervate more than one muscle |
Amplitude | range of muscle fiber length between max & min lengthening |
Gaster | Contractile portion of muscle |
Tendon | Fibrous connective tissue, connects muscles to bones, connects muscles to other structures |
Two muscles may share a tendon | Gastrochnemius and Soleus share the Achilles tendon |
A muscle may have multiple tendons connecting it to one or more bones | Three proximal attachments of triceps brachii. Allows muscles to diversify their actions by connecting to different heads. |
Origin | Where the muscle starts Structurally- most proximal attachment of muscle Functionally- least movable part of muscle |
Insertion | Where the muscle ends Structurally- the most distal attachment of muscle Functionally- Most moveable part of the muscle |
