Lumbar Spine, Sacrum, and Coccyx Below the sacrum is the tail end of your spine, called the coccyx or tailbone. Again, several fused vertebrae (generally 3–5) form the coccyx. Injury to this area can lead to coccydynia, which is a real pain in the you-know-what. Definition. Coccydynia is a painful condition involving swelling around your tailbone.

Sacrum For other uses, see Sacrum (disambiguation). The sacrum (/ˈsækrəm/ or /ˈseɪkrəm/; plural: sacra or sacrums; Latin os sacrum) in human anatomy is a large, triangular bone at the base of the spine, that forms by the fusing of sacral vertebrae S1–S5, between 18 and 30 years of age. The sacrum articulates (forms a joint) with four other bones.

Spinal Column - Anatomy & Physiology Sacral Vertebrae. The sacrum is a single bone formed by the fusion of several vertebrae that articulates with the pelvic girdle. It allows the thrust of the hindlimbs to be transmitted to the trunk. The sacrum narrows caudally and is curved to present a concave surface to the pelvic cavity.

Vertebral column The human vertebral column is the vertebral column (backbone or spine) of the human skeleton, consisting of 24 articulating vertebrae and 9 fused vertebrae in the sacrum and the coccyx.The vertebrae in the column are separated from each other by intervertebral discs.hese regions are called the cervical spine, thoracic spine, lumbar spine, sacrum and coccyx. There are a total of 33 vertebrae in the vertebral column. The articulating vertebrae are named according to their region of the spine.

Spine Basics The lowest part of the spine is called the lumbar spine. This area usually has 5 vertebrae. However, sometimes people are born with 6 vertebrae in the lumbar region. The base of your spine (called the sacrum) is a group of specialized vertebrae that connects the spine to the pelvis. When one of the bones forms as a vertebra rather than part of the sacrum, it is called a transitional (or sixth) vertebra.

- Sacrum: The sacrum is the wedge-shaped bone consisting of five fused vertebrae, the first of which has a prominent upper border known as the sacral promontory. This is an important pelvic landmark. It projects forward decreasing the anterposterior diameter of the pelvic brim. If this diameter is seriously decreased it can impair the descent of the fetal head into the pelvis. The smooth concave anterior surface is referred to as the hollow of the sacrum and the areas either side are the alae or wings. The convex posterior surface is roughened to receive attachments of muscles. The sacrum is perforated by four sets of holes or foramina through which the sacral nerves pass. Coccyx: The coccyx is at the lower part of the spine and is a vesitigal tail. It is a small triangular-shaped bone consisting of four fused vertebrae.

What is the anatomy of the spine? There are 33 total vertebrae in five sections: Each vertebra is named according to its section and its number from the top: C1 through C7, T1 through T12, L1 through L5 and the sacral-coccyx section, which are formed into one and are not movable.astly there is the sacral spine and then the coccyx, or tailbone. The intervertebral disks are shock absorbers which are located in between the vertebrae. The spinal nerves are nerves which exit out of the sides of the vertebrae at most levels through the spinal canal.

Sacral Insufficiency Fractures The sacrum forms the base of the spine and the center of the pelvis. The sacrum transmits the weight of the body to the pelvic girdle. It is shorter and wider in the female than in the male. Its name means sacred bone. At the top of the sacrum there are wings from each side called the sacral ala.

- The vertebral column is composed of a series of 31 separate bones known as vertebrae. There are seven cervical or neck vertebrae, 12 thoracic vertebrae, and five lumbar vertebrae. The sacrum is composed of five fused vertebrae, and there are two coccygeal vertebrae which are sometimes fused (fig.1). In the normal adult there are four curvatures in the vertebral column in an anteroposterior plane. These serve to align the head with a vertical line through the pelvis (fig. 2).he sacrum is composed of five fused vertebrae, and there are two coccygeal vertebrae which are sometimes fused (fig. 1).

Anatomy of the Human Spine Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

RIXIMKA DUMARKA In tetrapod anatomy, the sacrum (/ˈsaekrəm/ ˈsækrəm /or/ ; ˈseɪkrəm: plural sacra or; Sacrums latin os) sacrum is a, large triangular bone at the base of the spine and at the, upper back part of the pelvic, cavity where it is inserted like a wedge between the two hip. boneshe floor of the groove is formed by the united laminae of the corresponding vertebrae. The laminae of the fifth sacral vertebra, and sometimes those of the fourth, do not meet at the back, resulting in a fissure known as the sacral hiatus in the posterior wall of the sacral canal.
