What is a fossabone marking?
Fossa (pl. fossae A shallow depression. The word means "ditch" and "trench". These depressions on the bone's surface often receive another articulating bone with whom a joint can be formed. Types of bone marking: (Shallow) depression.
The bone marking is also known as a bone mark.
Bone marking. These projections provide attachment for muscles, ligaments, and projections that help to form joints.
What are bone markings, and why are they so important? They allow for muscle attachment as well as the passage of nerves. This allows for direct connection.
What is a fossa?
Fossa is Latin for "fossa", which means ditch or trench. It's a depression or hollow that occurs in a bone such as the hypophyseal or sphenoid fossa. A meatus is a small canal that connects to another part of your body. A fovea, Latin: pit, is a small hole located on the top of a bone.
What is a sulcus marking on a bone?
Ex: Intertubercular Sulcus, which is located between the two tubercles. It is the deep depression that houses the tendon of long head of biceps brachii muscles. Projections for tendon attachment. These include Crest, Epicondyle and Line, Process, Ramus (plural rami), Spine Trochanter, Tubercle and Tuberosity.

What is a bony prominence called?
bony prominence. Any point on the body where the bone is immediately below the skin surface, which can be: (1) Normal, these being known as bony landmarks; or. (2) Abnormal, which correspond to reactive outgrowths of bone (exostoses), benign tumours (e.g., osteoma) or malignant tumours (e.g., osteosarcoma).
What is process in bone?
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body.
What is a bone projection?
A projection is an area of a bone that projects above the surface of the bone. These are the attachment points for tendons and ligaments. A hole is an opening or groove in the bone that allows blood vessels and nerves to enter the bone.
How many bones are in the human body?
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.
What is a line in anatomy?
Anatomical "lines", theoretical lines drawn through structures, are also used to describe anatomical location. For example: The midaxillary line, a line running vertically down the surface of the body passing through the apex of the axilla (armpit).
What is the purpose of bone features?
The surfaces of bones bear projections, depressions, ridges, and various other features. A process (projection) on one bone may fit with a depression on a second bone to form a joint. Another process allows for the attachment of a muscle or ligament. Grooves and openings provide passageways for blood vessels or nerves.
How does a bone grow in thickness?
Bone Growth
Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. Even though bones stop growing in length in early adulthood, they can continue to increase in thickness or diameter throughout life in response to stress from increased muscle activity or to weight.Is calcaneus a short bone?
Short Bones Are Cube-shaped
The carpals in the wrist (scaphoid, lunate, triquetral, hamate, pisiform, capitate, trapezoid, and trapezium) and the tarsals in the ankles (calcaneus, talus, navicular, cuboid, lateral cuneiform, intermediate cuneiform, and medial cuneiform) are examples of short bones.How many types of Fossa are there?
The family Eupleridae contains just eight living species, thought to have evolved from a single ancestor which colonised Madagascar from the African mainland 18 – 24 million years ago. Madagascar's largest carnivore, the fossa is unusual-looking, rather like a cross between a dog and a cat.
What is the end of a bone called?
The end of the long bone is the epiphysis and the shaft is the diaphysis. When a human finishes growing these parts fuse together. The outside of the flat bone consists of a layer of connective tissue called the periosteum.
Where is the fossa bone located?
Each fossa accommodates a different part of the brain. The anterior cranial fossa is the most shallow and superior of the three cranial fossae. It lies superiorly over the nasal and orbital cavities. The fossa accommodates the anteroinferior portions of the frontal lobes of the brain.
What is the most common cause of fractures?
Most bone fractures are caused by falls and accidents. Bone fractures caused by disease are referred to as pathological fractures. A compound fracture is one that also causes injury to the overlying skin. There are a number of different types of fractures, including avulsion, comminuted, and hairline fractures.
What is another name for spongy bone?
Cancellous bone, also called trabecular or spongy bone, is the internal tissue of the skeletal bone and is an open cell porous network.
What does the fossa do?
It is solitary except during the breeding season. As a carnivore, the fossa is an excellent hunter. It preys on small- to medium-sized animals from fish to birds, mice, and wild pigs. But lemurs are its main food source, and the fossa is Madagascar's only predator able to kill the largest lemur species.
