What is a Ridgelike projection?
crest. a narrow, ridge-like projection.
What is a Thornlike projection in anatomy?
Spine. A thornlike projection. Suture. An interlocking line of union between bones.
What is a prominent projection on a bone?
A condyle is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone. The epicondyle refers to a projection near a condyle, particularly the medial epicondyle of the humerus.
What is narrow ridge like projection?
Terms used to describe the skeletal structure
| Question | Answer |
|---|---|
| narrow ridgelike projection | crest |
| projection situated above a condyle | epicondyle |
| small, nearly flat surface | facet |
| cleft or groove | fissure |
What are Tuberosities?
Tuberosity – A moderate prominence where muscles and connective tissues attach. Its function is similar to that of a trochanter. Examples include the tibial tuberosity, deltoid tuberosity, and ischial tuberosity.
Is a small smooth area on a bone?
A rounded prominence; especially : a large prominence on a bone usually serving for the attachment of muscles or ligaments. A small smooth area on a bone or other firm structure, usually an articular surface covered in life with articular cartilage. Fovea. A small cuplike depression or pit in a bone or organ.
What is a small Knoblike projection?
tubercle. projection for muscle attachment; small, rounded knoblike projection. tuberosity.
Is foramen a projection or depression?
Foramen – A hole through which nerves and blood vessels pass. Examples include supraorbital foramen, infraorbital foramen, and mental foramen on the cranium. Fossa – A shallow depression in the bone surface.
Is sulcus a projection or depression?
| MARKING | |
|---|---|
| Fossa | Shallow depression |
| Sulcus | Furrow or groove along a bone surface that accommodates a blood vessel, nerve or tendon |
| Meatus | Tube-like opening (passageway) |
| Processes: Projections or outgrowths on bone that form joints or are attachment points for connective tissue such as ligaments and tendons. |
Where are Tuberosities located?
The tubercle is much more prominent in the upper ribs than in the lower ribs. The most prominent tubercle of the tibia, a leg bone which is more commonly known as the shinbone or shankbone, is the tibial tuberosity. The tibial tuberosity is located on the tibia’s anterior surface, distal to the medial condyle.
What is Ramus?
Definition of ramus : a projecting part, elongated process, or branch: such as. a : the posterior more or less vertical part on each side of the lower jaw that articulates with the skull.
Are crests depression or projection?
