Terms | Definitions |
|---|---|
 voluntary muscle | striated muscle that can be controlled voluntarily |
| involuntary muscle | a muscle that contracts without conscious control and found in walls of internal organs such as the stomach, intestine, bladder and blood vessels (excluding the heart) |
| skeletal muscle | multinucleated, striated, voluntary muscle that enables conscious movement of an animal; the type of muscle that |
| cardiac muscle | Striated, involuntary muscle found only in the heart |
| smooth muscle | non-striated, involuntary muscle having only one nucleus; the type of muscle found in soft internal organs and structures. (cells do not have a striped appearance under microscopic examination like skeletal and cardiac muscle) |
| aponeurosis | a thin sheet of fibrous connective tissue associated with flat muscles such as those found in the abdominal wall |
| tendinous | consisting of tendons or resembling a tendon |
| atrophy | shrinkage (usually due to disuse or disease) |
| hypertrophy | enlargement |
| myoblasts | skeletal muscle fibers arise from embryonic cells. |
| hyperplasia | increase in the number of cells |
| bursa | a connective tissue sac containing synovial fluid, found between a tendon and underlying bone |
| tendon sheath | an elongated bursa that surrounds the tendon, found between a tendon and underlying bone |
| fleshy | apparent direct attachment of muscle to bone, but in reality very short tendons (ie: proximal aspect of long head of triceps) |
| superficial fascia | loose connective tissue that lies beneath skin; allows structure to change shape easily against one another; attachments of muscle to skin; principle site for fat storage |
| deep fascia | a dense connective tissue, much tougher fibrous sheets than superficial fascia, layer beneath superficial fascia which extends over most of the body; deep fascia and it's septa are unyeilding |
| pronation | appendage rotation so that the palmar or plantar surface of the paw faces laterally |
| supination | appendage rotation so that the palmar or plantar surface of the paw faces medially |
| septa | the cells that make up hyphae are divided by these cross sections |
| compartment syndrome | elevation of interstitial pressure within a closed compartment, that results in pain, micro-vascular compromise and can lead to damaged blood vessels, nerve and muscle cells. Occurs in humans, horses, cows and dogs. |
| flexion | angle of joint is reduced |
| extension | angle of joint is increased |
| flexor surface | the parts of the skin on the side of the joint where the angle of the joint is reduced |
| latissimus dorsi | origin - thoracolumbar fascia from spinous processes of lumbar and thoracic vertebrae insertion - proximal aspect of humerus |
| semitendinosus | flexes leg at the knee and extends thigh at the hip; belongs to the hamstring group |
| semimembranosus | flexes leg at the knee and extends thigh at the hip; belongs to the hamstring group |
| overextension or hyperextension | extension beyond 180 degrees |
| adduction | limb movement toward median plane |
| abduction | limb movement away from median plane |
| antagonist | blocks an action |
| agonist | produces an action |
| rotation | a joint movement that sonsists of a twisting motion of a part on its own axis |
| supination | turning of the palmar surface or plantar surface is upward or forward |
| pronation | turning of the palmar surface or plantar surface is downward or backward |
| flexion | bending at the joint so that the angle between the bones is decreased |
| extension | straightening at the joint so that the angle between the bones is increased |
| circumduction | circular movement of joint, combining movements; possible in shoulder joint, hip joint, and trunk around a fixing point |
