| external carotid nerves | A number of sympathetic nerve fibres conveyed via the cephalic arterial ramus of the sympathetic trunk which extends from the superior cervical ganglion to the external carotid artery, forming the external carotid plexus. Synonym: nervi carotici externi. (05 Mar 2000) |
|---|---|
| upper thoracic splanchnic nerves | Part of the cardiopulmonary splanchnic nerves from the second to fifth segments of the thoracic sympathetic trunk that pass medially and anteriorly to enter the cardiac plexus; they convey postsynaptic sympathetic fibres to, and visceral afferent (pain) fibres from, the heart. Synonym: nervi cardiaci thoracici, upper thoracic splanchnic nerves. (05 Mar 2000) |
| laryngeal nerves | Branches of the vagus nerve (the tenth cranial nerve). The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibres to the cricothyroid muscles, and internal branches, which carry sensory fibres. The recurrent (inferior) laryngeal nerve originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibres to the laryngeal, pharyngeal, tracheal, and cardiac regions. (12 Dec 1998) |
| lateral cutaneous branches of intercostal nerves | Branches arising in approximately the anterior axillary line at the level of the second through sixth intercostal spaces. Synonym: rami mammarii laterales nervorum intercostalium, lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral cutaneous branches of ventral primary ramus of thoracic spinal nerves | Branches arising in approximately the anterior axillary line at the level of the second through sixth intercostal spaces. Synonym: rami mammarii laterales nervorum intercostalium, lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of intercostal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lateral mammary branches of lateral cutaneous branches of thoracic spinal nerves | Branches arising from the lateral cutaneous branches of the ventral primary rami of spinal nerves (intercostal nerves) T-3 to T-6 which run anteriorly to supply the lateral aspect of the breast. Synonym: rami mammarii laterales rami cutanei lateralis nervorum thoracicorum, rami mammarii laterales rami cutanei lateralis nervorum intercostalium, lateral mammary branches of lateral cutaneous branches of intercostal nerves. (05 Mar 2000) |
| lesser palatine nerves | Usually two, these nerves emerge through the lesser palatine foramina and supply the mucosa and glands of the soft palate and uvula; they are branches of the pterygopalatine ganglion and contain postsynaptic parasympathetic and sensory fibres of the maxillary nerve. Synonym: nervi palatini minores. (05 Mar 2000) |
| loops of spinal nerves | Loops of the spinal nerves, connecting ventral primary rami of the spinal nerves. Synonym: ansae nervorum spinalium. (05 Mar 2000) |
| lumbar nerves | Five bilaterally-paired nerves emerging from the lumbar portion of the spinal cord; the first four nerves enter into the formation of the lumbar plexus, the fourth and fifth into that of the sacral plexus. Synonym: nervi lumbales. (05 Mar 2000) |
| lumbar splanchnic nerves | Branches from the lumbar sympathetic trunks that pass anteriorly to convey presynaptic sympathetic fibres to, and visceral afferents from, the coeliac, intermesenteric, aortic, and superior hypogastric plexuses. Synonym: nervi splanchnici lumbales. (05 Mar 2000) |
| absolute system of units | A system based on absolute units accepted as being fundamental (length, mass, time) and from which other units (force, energy or work, power) are derived; such system's in common use are the foot-pound-second, centimeter-gram-second, and meter-kilogram-second system's. (05 Mar 2000) |
| absorbent system | <anatomy> The tissues and organs (including the bone marrow, spleen, thymus and lymph nodes) that produce and store cells that fight infection and the network of vessels that carry lymph. (12 May 1997) |
| alimentary system | The organs that are responsible for getting food into and out of the body and for making use of food to keep the body healthy. These include the mouth, oesophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum. (12 Dec 1998) |
| anterolateral system | A composite bundle of fibres, located in the ventrolateral part of the lateral funiculus, containing spinothalamic, spinohypothalamic, spinoreticular, and spinomesencephalic (spinotectal, spinal to periaqueductal grey, etc.) fibres; occupies the combined areas of the spinal white matter historically divided into anterior and lateral spinothalamic tracts; located in white matter ventral to the denticulate ligament, hence the anatomical basis for the anterolateral cordotomy; concerned with the transmission of nociceptive and thermal information and with crude (nondiscriminative) touch.
