Remnants of cervical ribs secondarily fused to cervical vertebrae (the uppermost part of the vertebral column) are represented by part of the transverse process of the cervical vertebrae. The number of pairs of ribs in mammals varies from 9 (whale) to 24 (sloth); of true ribs, from 3 to 10 pairs. In humans there are normally 12 pairs of ribs.

    The first rib is the most superior of the twelve ribs. It is an atypical rib and is an important anatomical landmark and is one of the borders of the superior thoracic aperture. Typical ribs: 12 pairs, symmetrically arrayed; numbered in accordance with attached vertebral body, True ribs () attach to sternum by costal cartilages (synovial joints), False ribs () articulate by costal. transverse processes C7-T rib below its origin, medial to the angle: elevates the rib: dorsal primary rami of spinal nerves C7-T deep cervical a., intercostal aa. these are fairly small and insignificant muscles: subcostalis: angle of ribs: angle of a rib ribs above origin: compresses the intercostal spaces: intercostal nerves.

    Fibrocartilage discs located between the vertebrae act as shock absorbers. Openings in the transverse process, called the transverse foramina, allow large vessels and nerves ascending the neck to reach the brain. Connecting to the vertebral column are the 12 pairs of ribs that make up the thoracic cage. It was apparent the T3 vertebra was unable to glide forward on T4 during neck flexion causing the transverse process of T3 to rotate to the side of the motion restricted joint (Fig.4). Adhesive facets are usually an easy fix in acute cases but long term cartilage jamming may lead to tissue degradation, protective muscle splinting and.

Cervical ribs can be completely formed or rudimentary. In the latter case, there is almost always a compressive band of tissue extending to the first thoracic rib. As they project from transverse processes, cervical ribs displace the involved structures forward. Ribs 11 and 12 have no neck, no tubercles, and only one facet on the rib head articulating with the corresponding vertebral body.

Rib motion is influenced by the angle between the vertebral body and the transverse process as well as the distance between the costal articulations with the vertebrae. Rib motion is characterized by one of three.

The two transverse processes project laterally from the join between the pedicle and lamina and also serve as an attachment point for muscles and ligaments of the back.

The transverse processes articulate with the ribs in conjunction with the vertebral body. There are no ribs attached to them, though the remnants of ribs are incorporated into the transverse processes (L3 is typical, see Fig.

All the usual processes are present, with the dorsal spine forming a flat plate that runs the length of the vertebra in the sagittal plane. Thus, anterior rotation of ribs 7–10 relative to the transverse process requires a PMS glide.

Alternately, if the chosen motor control strategy significantly compresses the costotransverse joints, no motion may occur between the ribs and the relevant transverse process when the thoracic ring anteriorly tilts during forward bending of the by: 5.

Transverse processes of superior vertebrae and inferior surfaces of ribs: Extends vertebral column; alone, each produces lateral flexion to the side: Thoracic and lumbar spinal nerves: Illiocastalis thoracis: Superior borders of inferior seven ribs medial to the angles: Upper ribs and transverse process of last cervical vertebrae.

In some cases, T10’s transverse process does not have a facet to articulate with a rib. T11 only has one facet on each side of the vertebra for articulating with the rib head. Also, the transverse process lacks a facet to articulate with a rib. T12 also only has one facet on each side of the vertebra.

As part of the transition to the lower. The body receives the costal cartilage attachments for ribs 3–7. The small xiphoid process forms the inferior tip of the sternum. A typical rib is a flattened, curved bone. The head of a rib is attached posteriorly to the costal facets of the thoracic vertebrae.

The rib tubercle articulates with the transverse process of a thoracic vertebra. This muscle does not run the full spinal column and inserts on the 12th rib and the transverse processes of L1-L4 and bends the trunk, fixes the placement of the 12th rib and aids in respiration. The nerve innervation is the subcostal nerve, as well as the lumbar spinal nerves.

distal. Answer - Tubercle of rib articulates with transverse process of a vertebra Expalnation: Ribs have articulations anteriorly with sternum and posteriorly.

The transverse processes are bony projection bilaterally located which serve as attachment sites of muscles and ligaments. On the transverse process is the costal facet for the attachment of the rib, and it is the transverse process itself which is used to diagnose somatic dysfunctions.

Lumbar (or 13 th) ribs are a rare anatomical variant and represent transitional vertebrae at the thoracolumbar junction with a prevalence of ~1% It presents as an additional rib coming off T13 or L1 (depending on numbering classification) and may be unilateral or bilateral.

Lumbar ribs are mostly an asymptomatic incidental finding. The other costovertebral joint is that between the tubercle on the neck and the transverse process of the joining thoracic vertebra of the same rib number, and this is known as the costotransverse joint. The superior costotransverse ligament attaches from the non-articular facet of the tubercle to the transverse process of the vertebra.

erector spinae - spinalis. Furthermore, due to their rarity, lumbar ribs have often been mistaken for kissing osteophytes, abdominal vessel abnormalities, and/or fractures of the transverse processes [3,7]. The Neck of Typical Ribs • The neck contains no bony prominences, but simply connects the head with the body.

• It is located in front of the transverse process of the corresponding vertebra. • The neck has 2 borders – – Superior and inferior. • 2 surfaces– – Anterior and posterior. A small bump on the posterior rib surface is the tubercle of the rib, which articulates with the facet located on the transverse process of the same numbered vertebra.

The remainder of the rib is the body of the rib (shaft). Just lateral to the tubercle is the angle of the rib, the point at which the rib has its greatest degree of curvature. The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates, that encloses and protects the heart and humans, the rib cage, also known as the thoracic cage, is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton.
