Term
|
Definition
| Fascia that surrounds fascial compartments; contains muscles typically sharing function and vascular supply/innervation |
|
|
Term
|
Definition
| A layer of thick fascia that surrounds tendons at points they cross joints, preventing "bowstringing" (sliding across joint instead of transmitting force) |
|
|
Term
|
Definition
| closed, usually thin sacs of serous membrane. Examples include subtendinous bursae, synovial tendon sheaths. Serous membranes of ventral body cavity are histologically identical but not usually named as bursa. |

|
|
Term
|
Definition
| region of the posterior leg (knee to ankle) |
|
|
Term
|
Definition
| region between the pubic symphysis and the coccyx. |
|
|
Term
|
Definition
| Automatic contraction of a SKELETAL muscle; motor impulse generated in spinal column |
|
|
Term
|
Definition
| Constant, baseline contraction of a conscious individual's (skeletal) muscles |
|
|
Term
|
Definition
| a type of phasic contraction in which the muscle changes length during contraction |
|
|
Term
|
Definition
| Muscle is more tense than during tonic contraction, but not changing length. |
|
|
Term
| eccentric /concentric contraction |
|
Definition
| differentiates whether muscle is exerting force in the same direction or opposite direction of the extremities movement vector |
|
|
Term
|
Definition
| agonist of a motion; concentric contractor which expends the most work |
|
|
Term
|
Definition
| eccentric contracter during joint movement |
|
|
Term
|
Definition
| steadies proximal portion of a limb during distal contraction. During the contraction of the distal primary movers, the fixators contract isometrically |
|
|
Term
|
Definition
| outer layer of the blood vessel - connective tissue |
|
|
Term
|
Definition
| smooth muscle - blood vessel layer. Most variable layer, can have elastic fibers in arteries. |

Term
|
Definition
communications between multiple branches of an artery
etymology: to provide a mouth - "stoma" |
|
|
Term
|
Definition
| blood flows through a minor artery instead of through the more major artery with which it has ananastamosis. |
|
|
Term
|
Definition
| an interlacing network of small veins |
|
|
Term
|
Definition
| the 2 or several veins inside a vascular sheath (fascia) with a single artery. Arranged to facilitate counter-current heat exchange and arteriovenous pumping. |
|
|
Term
| arteriolovenular anastamosis |
|
Definition
| venous shunts - allows arterial blood to bypass capillary beds and returning directly to heart via venous system |
|
|
Term
|
Definition
| empties lymph from right upper quadrant into the right subclavian at the right venous angle (junction of internal jugular and subclavical) |
|
|
Term
|
Definition
| A duct from the merger of many lymphatic trunks that drains into the left venous angle (subclavian and internal jugular intersection). |
|
|
Term
| pseudounipolar nerve cell |
|
Definition
| Cell bodies "hang off" the colinear axon and dendrite, which convey information directly from the extremities to the CNS. Cell bodies are found in sensory ganglia. |
|
|
Term
|
Definition
|
|
Term
|
Definition
| sensory fibers (afferent) |
|
|
Term
|
Definition
| A mixed nerve splitting posteriorly off the junction of the anterior and posterior spinal nerve roots. Innervates the synovial joints of the spinal column, the deep intrinsic back muscles, and the overlying skin. |
|
|
Term
|
Definition
| conveys sensory (pain or subconscious) information from hollow organs and blood vessels to the CNS. |
|
|
Term
| general visceral efferent fibers |
|
Definition
| transmits contraction-modulating signal from CNS to smooth muscle fibers |
|
|
Term
| Divisions of the nervous system which convey information between extremities and CNS without interruption of a synpase |
|
Definition
| All sensory fibers and general somatic efferent (motor) |
|
|
Term
| the divisions of the nervous system in which information must cross a synapse (eg pre- and post-synaptic nerves are both used) between spinal column and extremity |
|
Definition
| Both sympathetic and parasympathetic ANS have pre- and post- synaptic neurons. |
|
|
Term
|
Definition
| transmitter used by parasympathetic nervous system |
|
|
Term
|
Definition
| transmitter used by sympathetic nervous system. |
|
|
Term
| communicating branches of anterior ramus |
|
Definition
| The tract sympathetic neurons follow almost immediately after entering the anterior ramus to reach the appropriate sympathetic ganglion (para- or pre-vertebral) |
|
