The iliac tubercle is located approximately 5 cm (2 in) posterior to the anterior superior iliac spine on the iliac crest in humans. [1] The transverse plane that includes each of the tubercles (one from the left iliac tubercle and one from the right iliac tubercle) is called the transtubercular plane .
It is thinner at the center than at the extremities, and ends in the anterior and posterior superior iliac spines. The surface of the crest is broad, and divided into external and internal lips, and an intermediate line. About 5 cm behind the anterior superior iliac spine there is a prominent tubercle on the outer lip.
The AON is found behind the olfactory bulb and in front of the piriform cortex (laterally) and olfactory tubercle (medially) in the olfactory tract (also olfactory peduncle) or retrobulbar area. [ 5 ] [ 6 ] The peduncle contains the AON as well as two other much smaller regions, the ventral and dorsal tenia tecta .
It refers to the anterior extremity of the iliac crest of the pelvis. It provides attachment for the inguinal ligament, and the sartorius muscle. [1] The tensor fasciae latae muscle attaches to the lateral aspect of the superior anterior iliac spine, and also about 5 cm away at the iliac tubercle. [2] [3]
The posterior inferior iliac spine (Sweeney's Tubercle) is an anatomical landmark that describes a bony "spine", or projection, at the posterior and inferior surface of the iliac bone. It is one of two such spines on the posterior surface, the other being the posterior superior iliac spine. These two spines are separated by a bony notch.
The iliac tuberosity is part of the anatomy of the ilium portion of the hip bone. Behind the iliac fossa is a rough surface, divided into two portions, an anterior and a posterior. [ 1 ] The posterior portion, the iliac tuberosity , is elevated and rough, for the attachment of the posterior sacroiliac ligaments and for the origins of the ...
This region of the brain is part of the limbic system, where it aids in the reinforcing effects of reward-like activities. Within most species, the islands are specifically located within the olfactory tubercle ; however, in primates, these islands are located within the nucleus accumbens , the reward center of the brain, since the olfactory ...
The anterior inferior iliac spine (AIIS) is a bony eminence on the anterior border of the hip bone, or, more precisely, the wing of the ilium. Structure [ edit ]
