What are the bone markings of the femur?
| Marking | Location |
|---|---|
| Head | Smooth, rounded structure at the proximal end of the femur |
| Neck | Constricted area distal to the femoral head |
| Greater trochanter | Large process that projects superiorly from the neck of the femur |
| Gluteal tuberosity | -Roughened area on posterior surface of femur -Located at superior end of the linea aspera |
What are the three major femur 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”).
Which bone markings can you identify on the thoracic vertebrae?
The thoracic vertebrae all have structure (or bone marking) located laterally on each side, called the demifacets. The demifacets of the thoracic vertebrae are articulation points for the ribs.
What marking is found only on the femur?
Trochanter
Trochanter. This landmark is present only in the femur and it refers to a very large, blunt, irregularly shaped process of the femur that serves as an attachment point for muscles and ligaments. On the femur there is a greater trochanter and a less prominent lesser trochanter.
Which features are found only on thoracic vertebrae?
Thoracic vertebrae are unique among the bones of the spine in that they are the only vertebrae that support ribs and have overlapping spinous processes.
Where are the thoracic vertebrae located?
Your thoracic spine is located in the center of your upper and middle back. It begins at the base of your neck (cervical spine) and ends around the bottom of your rib cage, just above your lower back (lumbar spine).
What markings are on the medial side of the femur?
On the medial, proximal, posterior part of the femur is another (smaller ridge) known as the pectineal line. It acts as the point of attachment for the pectineus muscle. The most pronounced part of the posterior surface is the linea aspera.
Which markings are clearly visible from the posterior view of the femur?
Linea aspera (Linea aspera) is a vertical ridge that runs along the midline of the femur’s posterior surface.
Where are thoracic vertebrae located?
What unique feature is present only on the thoracic vertebrae quizlet?
What unique feature is present only on the thoracic vertebrae? manubrium, body, xiphoid process. In the vertebral column, there are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 fused sacral vertebrae, and 3-5 fused coccygeal vertebra to make an average total of 33 vertebrae in an older adult.
What is the structure of the thoracic vertebrae?
Your thoracic spine consists of 12 vertebrae, labeled T1 through T12. Vertebrae are the 33 individual, interlocking bones that form your spinal column. These bones help protect your spinal cord from injury while allowing you to twist and turn.
What are 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.
How many thoracic vertebrae are there?
12 vertebrae
The thoracic region contains 12 vertebrae, denoted T1-T12. The intervertebral discs, along with the laminae, pedicles, and articular processes of adjacent vertebrae, create a space through which spinal nerves exit. The thoracic vertebrae, as a group, produce a kyphotic curve.
Which of these features is only found on thoracic vertebrae?
Which of the following features are found on thoracic vertebrae?
The primary characteristic of the thoracic vertebrae is the presence of costal facets. There are six facets per thoracic vertebrae: two on the transverse processes and four demifacets—the facets of the transverse processes articulate with the tubercle of the associated rib.
How many thoracic vertebrae is there?
The thoracic region contains 12 vertebrae, denoted T1-T12.
