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 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 interatrial septum is a septum that lies between the left atrium and right atrium of the human heart.The interatrial septum lies at angle of 65 degrees from right posterior to left anterior because right atrium is located at the right side of the body while left atrium is located at the left side of the body.

This function is so significant to normal functioning of the circulatory system that the cardiovascular centre is considered a vital centre of the medulla oblongata. [ 2 ] [ 3 ] Hormones like epinephrine and norepinephrine can affect the cardiovascular centre and cause it to increase the rate of impulses sent to the sinoatrial node , resulting ...
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The iliac fossa is bounded above by the iliac crest, and below by the arcuate line. It is bordered in front and behind by the anterior and posterior borders of the ilium. The iliac fossa gives origin to the iliacus muscle. [1] The obturator nerve passes around the iliac fossa. [2] It is perforated at its inner part by a nutrient canal.
Real-time MRI of the human heart The human heart is in the middle of the thorax, with its apex pointing to the left. [15] The human heart is situated in the mediastinum, at the level of thoracic vertebrae T5–T8. A double-membraned sac called the pericardium surrounds the heart and attaches to the mediastinum. [16]
