What is ramus In anatomy

In anatomy as well as in medicine, the term ramus is often given to any branch or division that occurs in a blood vessel or nerve. This word is also used to describe a part of a bone that has an irregular shape but is considered to be thicker than the structure referred to as a process Two vertical portions (rami) form movable hinge joints on either side of the head, articulating with the glenoid cavity of the temporal bone of the skull. The rami also provide attachment for muscles important in chewing. The centre front of the arch is thickened and buttressed to for Ramus: In anatomy, a branch, such as a branch of a blood vessel or nerve. For example, the ramus acetabularis arteriae circumflexae femoris medialis is the branch of an artery that goes to the socket of the hip joint. The plural of ramus is rami.

The mandibular ramus is a portion of the mandible, or jawbone. As the bone that stretches from the underside of either ear and gives rise to the bottom teeth, the mandible consists of the body, which is the horizontal portion crossing the chin, and the ramus, the vertical section beneath each ear The ramus intermedius is a variant coronary artery resulting from trifurcation of the left main coronary artery schematron.org is present in ~20% (range %) of the population The third artery: Normally the main coronary blood vessel has two branches--the left anterior descending artery and left circumflex, but some people have a third branch termed intermediate artery or ramus-coronary artery--see picture. The incidence is some where between 10-30%. This can cause some confusion in ekg interpretation if this vessel is blocked/causing a heart attack What is the significance of ramus for an interventional cardiologist ? PCI in ramus is a rare opportunity for a cardiologist .The issue here is, if ramus is involved adjacent LAD and LCX is also likely to be involved .So it would logically be a multivessel , complex angioplasty.Isolated ramus lesion could be tackled easily.Another issue here.

The medial branches (ramus medialis) of the posterior branches of the upper six thoracic nerves run between the semispinalis dorsi and multifidus, which they supply. They then pierce the rhomboid and trapezius muscles, and reach the skin by the sides of the spinous processes. This branch is called the medial cutaneous ramus The ischiopubic ramus is the area where the ischium and the pubis join. This rear portion is also where the pubic tubercle is located, which is a small bump where muscles and ligaments attach to. The area of the pubis where the pubic bone meets with the ilium is an angle called the superior pubic ramus

  1. The pubic rami are four bones at the front of the pubic area that protect internal organs like the bladder. The pubic rami are a group of bones that make up a portion of the pelvic bone. Each of these bones, when referred to individually, is known as a pubic ramus
  2. The inferior ramus is the portion of the pubic bone that extends downwards and merges with the ramus of the ischium. The superior ramus of the pubis is the portion extending anteriorly from the body of the pubic bone. The superior ramus of the pubic bone features the following landmarks
  3. The ramus intermedius is a variant coronary artery resulting from trifurcation of the left main coronary artery 1. It is present in ~20% (range 15-30%) 2-3 of the population

Ramus of Mandible The body of each ramus goes downward from the top of the rami. The mandibular foramen is found on the inside of the body of the ramus, which is the beginning of the internal oblique ridge. The internal oblique ridge a.k.a. the mylohyoid ridge along with the body of the mandible travels along with the inner side of the ramus The mandibular notch is a depression located on the ramus of the mandible separating the condylar and coronoid processes. The ramus of the mandible also has an internal and an external surface. The internal surface of the ramus of the mandible features: mandibular foramen (leads into the mandibular canal) RAMUS.

Inferior Pubic Ramus (Ramus inferior ossis pubis) is a thin, flat, downward extension that runs diagonally from the medial pubis to the ischial ramus. The adductor brevis, adductor magnus, and gracilis muscles attach to this ramus The inferior pubic ramus connects to the ramus of the ischium, forming the ischiopubic ramus. The angle at which both of these converge is called the pubic arch. Next is the pubic crest, which is a thickening on the anterior part of the pubis where the abdominal muscles attach

The inferior pubic ramus joins the ischial ramus to form the ischiopubic ramus. The subpubic angle is formed by the medial convergence of the right and left ischiopubic rami.

This article reviews the relationship between the spinal dorsal ramus system and low back pain, including the anatomy, clinical findings, pathogenesis and treatment of low back pain mediated by spinal dorsal ramus and zygapophysial (facet) joint syndrome. Each spinal dorsal ramus arises from the spinal nerve and then divides into a medial and lateral branch Inferior ramus - The inferior ramus is the lower portion of the pubis that branches out. Obturator foramen - These two rami of the pubis join the ischium, forming a large hole in the hip bone called the obturator foramen. The word foramen refers to a hole in a bone, and this is the largest bone hole in the human body Pubic Ramus Fracture What we commonly call our hip bones are actually each three separate bones: the pubis, the ischium, and the ilium.

The pelvis is a group of fused bones and may be considered the first step in the linkage of the axial skeleton (bones of the head, neck, and vertebrae) to the lower appendages. The part of the axial skeleton directly communicating with the pelvis is the lumbar spinal column. The femur is the appendicular skeletal bone connected to the pelvis at the acetabulum, a bony ring formed by the fusion. Male Genital Anatomy. The penis is composed of 3 spongy cylinders. The three cylinders consist of paired corpora cavernosa and a single corpus spongiosum. The crural (roots) of the corpora cavernosa attach at the under surface of the ischiopubic rami as two separate structures. Such anatomy prevents the erect penis from sinking into the. Postganglionic axons leave sympathetic chain ganglia via a gray ramus communicans (called gray because the postganglionic neurons are not myelinated which gives a grayish appearance to the bridge) and enter a spinal nerve.
