Midaxillary line: A vertical line passing through the apex of the axilla. Posterior axillary line: A vertical line passing through the posterior axillary fold. Scapular line: A vertical line passing through the inferior angle of the scapula. Paravertebral line: A vertical line corresponding to the tips of the transverse processes of the vertebrae.
The cranial part of the septum transversum gives rise to the central tendon of the diaphragm, [1] and is the origin of the myoblasts that invade the pleuroperitoneal folds resulting in the formation of the muscular diaphragm.
It is wider superiorly than inferiorly. [2] It supports the rete testis and blood and lymphatic vessels of the testis in their passage into and out of the substance of the gland. [3] The septa testis - extensions of the tunica albuginea into the substance of the testis that form fibrous partitions - converge towards the mediastinum testis. [3]
In humans, reference may take origin from superficial anatomy, made to anatomical landmarks that are on the skin or visible underneath. As with planes, lines and points are imaginary. Examples include: The midaxillary line, a line running vertically down the surface of the body passing through the apex of the axilla (armpit).
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]
The tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [1] [4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).
The combination of surface tension, oncotic pressure, and the fluid pressure drop caused by the inward elastic recoil of the lung parenchyma and the rigidity of the chest wall, results in a normally negative pressure of -5 cm H 2 O (approximately −3.68 mmHg or −0.491 kPa) within the pleural space, causing it to mostly stay collapsed as a ...
