List Anatomy – I
The Isthmus of the rhomboid brain (istmus rhombencephali - BNA) unites formations formed on the border of the middle and rhomboid brain.
The ischium bone (os ischii) has a thickened body (corpus ossis ischii), which completes the acetabulum from below and moves to the ischium (ramus ossis ischu) branch anteriorly.
Iris is the most anterior part of the choroid, visible through a transparent cornea. It has the form of a disk with a thickness of about 0.4 mm, placed in the frontal plane.
The internal blocking muscle (m.obturatorius internus) begins at the edges of the occlusal opening (with the exception of the locking groove), on the inner surface of the obturator's membrane, on the pelvic surface of the ilium (above the occlusion aperture) and on the occlusal fascia.
Internal intercostal muscles (mm. Intercostales interni) are located inward from the external intercostal muscles. They occupy the intercostal spaces, starting from the edge of the sternum (at the true ribs) and the anterior ends of the cartilages of the false ribs and to the corners of the ribs from the rear, where the inner intercostal membrane (membrane intercostalis interna) serves as a continuation.
The internal carotid artery (a.carotis interna) supplies the brain and the organ of vision. The internal carotid artery is distinguished by cervical, stony, cavernous and cerebral parts. On the neck, this artery does not give branches.
The intersporeal muscles of the waist, chest and neck (mm., Intertransversari lumborum, thoracis et cervicis) are formed by short beams connecting the transverse processes of adjacent vertebrae, are better expressed at the level of the lumbar and cervical spine.
Intercostal nerves (nn. Intercostales) are directed laterally and forward in the intercostal spaces, the subcostal nerve - under the XII rib. Each intercostal nerve passes at the lower edge of the corresponding rib under the same artery and vein.
The internal oblique abdominal muscle (m. Obhquus internus abdominis) is located inside of the outer oblique abdominal muscle, forming the second layer of abdominal wall muscles. The muscle begins on the intermediate line of the iliac crest, the lumbosacral fascia and the lateral half of the inguinal ligament.
The inguinal canal (canalis inguinalis) is an obliquely slotted gap between the lower edges of the broad muscles, the transverse fascia and the inguinal ligament, in which the men have a seminal cord, and the women have a round ligament of the uterus.
The iliac bone (os ilium) consists of two sections. The lower thickened section - the body of the ilium (corpus ossis ilii) - participates in the formation of the acetabulum. Upper, dilated section is the wing of the ilium (ala ossis ilii).
The ilio-lumbar muscle (m.iliopsoas) consists of two muscles - the large lumbar and iliac, which, starting at different places (on the lumbar vertebrae and iliac bone), unite into a single muscle that attaches to the small trochanter of the femur.
