| 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.

| lateral mammary branches of lateral thoracic artery | <anatomy, artery> Branches of the lateral thoracic artery which extend around the lateral borders of the pectoral muscles to supply the lateral aspect of the breast and mammary gland. Synonym: rami mammarii laterales arteriae thoracicae lateralis. (05 Mar 2000) |
| lateral vein of lateral ventricle | A vein draining deep portions of the temporal and parietal lobes; it runs in the lateral wall of the lateral ventricle to terminate in the superior thalamostriate vein. Synonym: vena ventriculi lateralis lateralis, lateral atrial vein, lateral vein of lateral ventricle. (05 Mar 2000) |
| reflected inguinal ligament | <anatomy> A triangular fibrous band extending from the aponeurosis of the external oblique to the pubic tubercle of the opposite side. See: aponeurosis of external abdominal oblique muscle. Synonym: ligamentum reflexum, Colles' ligament, fascia triangularis abdominis, reflex ligament, triangular fascia. (05 Mar 2000) |
| medial inguinal fossa | A depression on the peritoneal surface of the anterior abdominal wall between the ridges formed by the inferior epigastric artery and the medial umbilical ligament; it corresponds to the position of the superficial inguinal ring and is the site of a direct inguinal hernia. Synonym: fossa inguinalis medialis, fovea inguinalis interna. (05 Mar 2000) |
| properitoneal inguinal hernia | A complicated hernia having a double sac, one part in the inguinal canal, the other projecting from the internal inguinal ring in the subperitoneal tissues. Synonym: hernia en bissac, Kronlein's hernia. (05 Mar 2000) |
| deep inguinal lymph nodes | Several small nodes deep to the fascia lata and medial to the femoral vein; they receive lymph from the deep structures of the lower limb, from the glans penis and from superficial inguinal nodes; efferents pass to the external iliac nodes. Synonym: nodi lymphatici inguinales profundi. (05 Mar 2000) |
| direct inguinal hernia | See: inguinal hernia. (05 Mar 2000) |
| indirect inguinal hernia | <surgery> The abnormal passage of an internal abdominal organ or structure through the inguinal canal. In males, this will result in a unilateral bulge in the scrotum, in females there will be unilateral swelling in the region of the labia majora. Inguinal hernias are classified as direct or indirect on the basis of the anatomic path the hernia undertakes through the inguinal canal. Many hernias will reduce (go away) on their own but return at times of straining or lifting. A hernia that does not go away and causes pain is a surgical emergency. (27 Sep 1997) |
| inguinal | <anatomy> Pertaining to the inguen or groin. Origin: L. Inguinalis (05 May 1997) |
| inguinal aponeurotic fold | Common tendon of insertion of the transversus and obliquus internus muscles into the crest and spine of the pubis and iliopectineal line; it is frequently muscular rather than aponeurotic and may be poorly developed; forms posterior wall of medial inguinal canal. See: aponeurosis of internal abdominal oblique muscle. Synonym: falx inguinalis, tendo conjunctivus, conjoined tendon, falx aponeurotica, inguinal aponeurotic fold. Contracted tendon, a condition of young horses in which the flexor tendon's of the leg are shortened. (05 Mar 2000) |
| inguinal branches of external pudendal arteries | Branches to the inguinal region which may arise as branches of external pudendal arteries or as direct branches of the femoral artery. Supply skin and subcutaneous tissues, including inguinal lymph nodes. Synonym: rami inguinales arteriae pudendae externae. (05 Mar 2000) |
| inguinal canal | A passage in the lower anterior abdominal wall which in the male allows passage of the spermatic cord and in the female contains the round ligament. Because of the weakness it creates in the abdominal wall, it is the most frequent site for a hernia. (12 Dec 1998) |
| inguinal crest | An elevation in the body wall of the embryo at the internal opening of the inguinal canal; part of the gubernaculum testis develops within it. (05 Mar 2000) |
| inguinal fold | An embryonic mesodermal thickening that joins the caudal end of the urogenital ridge to the anterior abdominal wall; the gubernaculum of the testis develops in it. Synonym: inguinal fold. (05 Mar 2000) |
