What are iliac crests?
Crests can be described as prominent, raised edges of a bone. They are of medium thickness and often found at sites where connective tissue connects muscle and bone. The iliac crest is one example.
What is the function of bone markings?
The functionality of bone markings ranges from enabling joints to slide past each other or lock bones in place, providing structural support to muscle and connective tissue, and providing circumferential stabilization and protection to nerves, vessels, and connective tissue.
What are the different types of bone marking?
Common Bone Markings Angles - Sharp bony angulations which may serve as bony or soft tissue attachments but often are used for precise anatomical description. Examples include the superior, inferior, and acromial angles of the scapula and the superior, inferior, lateral angles of the occiput.
What is the importance of bony landmarks?
Their importance comes when we try to describe the shape of the bone or to understand how the muscles , ligaments and other structures affect this bone and vice versa. This article will discuss their anatomy , including the two broad categories of bony landmarks, their subtypes, features and examples.
What is bone marking?
Bone markings are invaluable to the identification of individual bones and bony pieces and aid in the understanding of functional and evolutionary anatomy. They are used by clinicians and surgeons, especially orthopedists, radiologists, forensic scientists, detectives, osteologists, and anatomists. ….
What are some examples of bony markings?
Examples include the superior, inferior, and acromial angles of the scapula and the superior, inferior, lateral angles of the occiput.
What is the articulating bone that slides into and out of the notch?
The articulating bone will slide into and out of the notch, guiding the range of motion of the joint. Examples include the trochlear notch on the ulna, radial notch of the ulna, suprasternal notch, and the mandibular notch. Ramus - The curved part of a bone that gives structural support to the rest of the bone.
What is the edge of the occipital bone called?
And vice versa, the edge of the occipital bone articulating with the temporal bone is called the temporal margin of the occipital bone. Meatus - A tube-like channel that extends within the bone, which may provide passage and protection to nerves, vessels, and even sound.
What is the margin of a bone?
It is the main articulating surface with the adjacent bone, forming a "ball-and-socket" joint. Margin - The edge of any flat bone. It can be used to define a bone's borders accurately. For example, the edge of the temporal bone articulating with the occipital bone is called the occipital margin of the temporal bone.
What is the head of a bone?
Head - A rounded, prominent extension of bone that forms part of a joint. It is separated from the shaft of the bone by the neck. The head is usually covered in hyaline cartilage inside a synovial capsule. It is the main articulating surface with the adjacent bone, forming a "ball-and-socket" joint.
What is a facet joint?
Facet - A smooth, flat surface that forms a joint with another flat bone or another facet, together creating a gliding joint. Examples can be seen in the facet joints of the vertebrae, which allow for flexion and extension of the spine. Fissure - An open slit in a bone that usually houses nerves and blood vessels.
