The innermost intercostal muscle is a layer of intercostal muscles. [1] It may also be called the intima of the internal intercostal muscles . [ 2 ] It is the deepest muscular layer of the thorax , [ 3 ] with muscle fibres running vertically (in parallel with the internal intercostal muscles ). [ 2 ]
The internal intercostal muscles (intercostales interni) are a group of skeletal muscles located between the ribs.They are eleven in number on either side. They commence anteriorly at the sternum, in the intercostal spaces between the cartilages of the true ribs, and at the anterior extremities of the cartilages of the false ribs, and extend backward as far as the angles of the ribs, hence ...
In reference to the muscles of the thoracic wall, the intercostal nerves and vessels run posterior to the internal intercostal muscles: therefore, they are generally covered on the inside by the parietal pleura, except when they are covered by the innermost intercostal muscles, innermost intercostal membrane, subcostal muscles or the transversus thoracis muscle.
The eyes sit in bony cavities called the orbits, in the skull. There are six extraocular muscles that control eye movements. The front visible part of the eye is made up of the whitish sclera, a coloured iris, and the pupil. A thin layer called the conjunctiva sits on top of this. The front part is also called the anterior segment of the eye.
The intercostal muscles comprise many different groups of muscles that run between the ribs, and help form and move the chest wall. The intercostal muscles are mainly involved in the mechanical aspect of breathing by helping expand and shrink the size of the chest cavity .
In eyes where the vitreous has fully or partially detached from the retina, this is the space created between the posterior cortical vitreous face and the internal limiting membrane of the retina. Hypo-reflective [25] 3: Internal limiting membrane (ILM) Formed by Müller cell endfeet (unclear if it can be observed on OCT) Hyper-reflective No [25]
The following outline is provided as an overview of and topical guide to human anatomy: . Human anatomy is the scientific study of the morphology of the adult human.It is subdivided into gross anatomy and microscopic anatomy.
The lacrimal bone also contains the nasolacrimal duct. The superior bony margin of the orbital rim, otherwise known as the orbital process, is formed by the frontal bone. [7] The roof (superior wall) is formed primarily by the orbital plate frontal bone, and also the lesser wing of sphenoid near the apex of the orbit. The orbital surface ...
