What are bone surface markings used for?
Bone markings are very important since they allow for identification of bones and bony pieces, enable joints to form, enable bones to slide past each other, enable bones to lock in place, and provide places for muscle and connective tissues to attach and provide structural support.
What terms are used to describe bone markings?
1). There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).
What are the 7 bone markings?

What are some examples of various bone markings?
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. Examples include the superior/inferior pubic ramus and ramus of the mandible.
What are the two categories of bone markings Nasm?
Name the two different types of bone markings….
- Gliding.
- Hinge.
- Pivot.
- Condyloid.
- Saddle.
- Ball and Socket.
What is the bone marking shown at letter C?
In the neck, there are seven cervical vertebrae, each designated with the letter “C” followed by its number. Superiorly, the C1 vertebra articulates (forms a joint) with the occipital condyles of the skull. Inferiorly, C1 articulates with the C2 vertebra, and so on.
What is a bone marking?
Bone markings are projections and depressions found on bones, which help us to identify the location of other body structures, such as muscles. 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.
What are bony landmarks?
Any place on the skin surface where the underlying bone is normally close to the surface and easily palpable.
Which of the following are the two most important functions of the skeletal system Nasm?
Bones serve two vital functions – leverage and support. Remodeling – Process of resorption and formation of bone. Old bone is broken down and removed by osteoclasts, new bone is laid down by cells called osteoblasts.
What is appendicular skeletal system?
The appendicular skeleton is the portion of the skeleton of vertebrates consisting of the bones that support the appendages. There are 126 bones. The appendicular skeleton includes the skeletal elements within the limbs, as well as supporting shoulder girdle and pelvic girdle.
What is the fibrocartilage padding in between the vertebrae called?
An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
What are all the bone markings?
There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”). These surfaces tend to conform to one another, such as one being rounded and the other cupped, to facilitate the function of the articulation.
What are surface markings?
Surface markings are unique structural features that serve as anatomical landmarks. There are 2 types: 1) Depressions and openings – usually allow passage of blood vessels and nerves or help form joints. 2) Processes – projections that either help form joints or serve as attachment points for ligaments and tendons.
What is bone marking process?
Ulna Bone Markings: Olecranon or olecranon process (olecranon ulnae) is a large, fan-shaped superior projection from the proximal end of the ulna. Its curved anterior surface forms the superior portion of the trochlear notch (see below) and its rounded posterior surface forms the bump of the elbow.
What is groove bone marking?
In general, their size and shape is an indication of the forces exerted through the attachment to the bone. A hole is an opening or groove in the bone that allows blood vessels and nerves to enter the bone. As with the other markings, their size and shape reflect the size of the vessels and nerves that penetrate the bone at these points.
