Introduction to Axis Bone Anatomy: Inferior to the atlas bone (C1) is the second cervical vertebra (C2), which is also referred to as the axis bone (axis, vertebra cervicalis II).. One of the most prominent features of the axis bone is a superior, tooth-like projection called the odontoid process (or dens).. Osteocytes regulate mineral homeostasis. 17) A projection at an angle on a bone is termed a E) ramus. Bones work in concert with tendons, joints, ligaments, and … patella. ; This arrangement permits flexion and extension movements but limits rotation. Most bones have some combination of bumps, ridges, projections, depressions, cavities, and holes in them that help them carry out their functions. Bones come in a variety of shapes and sizes and have a complex internal and external structure. Any bony prominence[image] Term.

Osteoclasts have a " ruffled border" and are multinucleated. Several muscles of the upper and lower arm attach at the elbow on the olecranon process. Ethmoid bone – It is the bone inside the eye cavity just behind the bridge of the nose. ; The spinous processes are broad and thick so stabilizing muscles can attach. Short bones. It has a honeycomb-like matrix internally, which helps to give the bone … The bodies of the lumbar vertebrae are massive, sturdy, and designed to withstand vertical compression. According to Right Diagnosis, bony processes are parts of bones that stick out from the main body of the bone, serving as attachment sites for muscles, ligaments or other connective tissues. Zygomatic bone, also called cheekbone, or malar bone, diamond-shaped bone below and lateral to the orbit, or eye socket, at the widest part of the cheek. spine. The red bone marrow inside larger bones, such as the scapulae, is the site of production of red blood cells. Bones come in all shapes and sizes and have many roles. Overview.

Study Answer the Anatomy of Bone Markings Projections, Depressions,Openings Flashcards Flashcards at ProProfs - Different projections for joints, muscles, ligaments They are responsible for the body's height. Fat deposition and blood sugar levels are also controlled by the bones through the release of osteocalcin hormone, which is known to increase insulin production and help reduce excessive fat storage. The Olecranon Process is the bony projection of the ulna bone that can be felt at the elbow. Like other long bones, the fibula has a proximal end (with a head and neck), a shaft, and a distal end. The functions of bone include (1) structural support for the mechanical action of soft tissues, such as the contraction of muscles and the expansion of lungs, (2) protection of soft organs and tissues, as by the skull, (3) provision of a protective site for specialized tissues such as the blood-forming system (bone marrow), and (4) a mineral reservoir, whereby the endocrine system regulates the level of calcium and … Bony expansion carried on a narrow neck [image] Term. In general, their size and shape is an indication of the forces exerted through the attachment to the bone. A ramus is the curved surface of a bone, and it is only found on the axial skeleton. (Red blood cells, white blood cells and blood platelets are described on structure and functions of blood.) What are some irregular bones? The axis derives its name from the large pointed projection of bone, called the dens, which literally functions as the vertical axis of rotation for rotary movements between the head and the upper cervical region (see Figure 8-12). The surface features of bones vary considerably, depending on the function and location in the body. Fossae can be found on both the axial and appendicular skeletons. What is an example of a sesamoid bone? Long bones function as levers; they move when muscles contract. 6. process [pros´es] 1. a prominence or projection, as from a bone. The superior facets of the axis (C2) are relatively flat, matching the flattened inferior facets of the atlas. They are responsible for bone growth and the uptake of minerals from the blood. Pivot joints occur when a projection of one bone articulates with a ring or notch of another bone. In the posterior compartment of the upper arm, the three heads of the triceps brachii converge into a single tendon that connects here. The mastoid process is a pyramidal bony projection from the posterior section of the temporal bone.The superior border of the mastoid portion of the temporal bone articulates with the parietal bone.. 14) The humerus is an example of a(n) _____ bone.
