What are the 3 types of 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”).
What causes bone markings?
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 is a spine bone marking?
Spine or Spinous process. Similar to a crest but raised higher; a sharp, pointed, slender projection. Such sharp raised projections called spines are often sites for muscle attachment. Types of Bone Marking: Process – attach connective tissues.
What are some common bone surface markings?
As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”)….Learning Objectives.
| Bone Markings (Table 7.2) | ||
|---|---|---|
| Marking | Description | Example |
| Facet | Flat surface | Vertebrae |
| Condyle | Rounded surface | Occipital condyles |
| Projections | Raised markings | Spinous process of the vertebrae |
What are bone landmarks?
Any place on the skin surface where the underlying bone is normally close to the surface and easily palpable. Palpation of Bony Landmarks—Upper extremity. Scapula: 1.

What are some of the bone markings and what are their importance?
Many of the bones include external markings or features – projections, depressions, and openings. Depending on their structure, these markings may serve as attachment sites for muscles, ligaments, and tendons or as passageways for blood vessels and nervous tissue.
What are five bony landmarks?
Here are some key bony landmarks to identify:
- Clavicle. Clavicles are more defined in some than others, but most characters should at least have a hint of them.
- Costal Cartilage. Costal cartilage connects the sternum and the ends of the ribs.
- Spine of Scapula.
- 7th Cervical Vertebra.
- Greater Trochanter.
- Sacral Triangle.
What are landmarks in anatomy?
Anatomical landmarks are defined as biologically meaningful loci that can be unambiguously defined and repeatedly located with a high degree of accuracy and precision. The relative location of landmarks provides a spatial map of the relative location of the features that the landmarks represent.
What are the 6 bony landmarks?
The most observable are the head, neck, greater trochanter, lesser trochanter, linea aspera, condyles, and epicondyles. These landmarks function as parts of joints and muscle attachment points.
What are the bony landmarks of the body?
Hard surface forms are also known as bony landmarks—parts of bones (ridges, bumps, depressions) that are positioned close to the skin, creating visual landmarks on the surface form.
