What is a hole or opening in a bone called?
What is a hole or opening in a bone called?
A foramen is any opening, particularly referring to those in bone. Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.
What are the holes in bones for?
Bones have tiny holes in their surface which allow the blood vessels and nerves to get in and out, thus to connect with blood circulation or the central nervous system, respectively.
Which type of bone tissue has holes and open spaces?
spongy
Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution.
What are bone openings?
Foramina (sing: foramen) are holes or openings in a bone, usually through which nerves and blood vessels pass.
What is the shaft of a bone called?
medullary cavity. The shaft of a long bone is called the diaphysis.
What is the difference between tubercle and tuberosity?
The main difference between tuberosity and tubercle is that tuberosity refers to a slightly larger lump on bones, but tubercle refers to the smaller lump. Some of the examples of tuberosity are the greater tuberosity of the humerus and the ischial tuberosity of the hip bone.
What is a shaft in a bone?
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.
Why do bones remodel themselves?
Bone remodeling serves to adjust bone architecture to meet changing mechanical needs and it helps to repair microdamages in bone matrix preventing the accumulation of old bone. It also plays an important role in maintaining plasma calcium homeostasis. The regulation of bone remodeling is both systemic and local.
Is an opening in bone through which blood vessels and nerves pass?
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.
What are bone cavities called?
Medullary Cavity
The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity….

What is a bone line?
The “bone line” is what automotive designers refer to when talking about the hard, almost sharp line that runs across the profile of most modern cars, and should not to be confused with the “belt line,” which is represented by the junction of the upper glass area and lower bodywork – the so-called shoulder line.
What is the opening of a bone called?
The narrow, slit-like (cleft-like) opening between two bones is called a fissure. It’s a bone marking that forms a passageway for blood vessels and nerves.
What is a hole in a bone called?
The Ethmoid bone (ethmos=sieve, mesh-like) The ethmoid bone is a tiny bone that has tiny little holes such as the olfactory foramina. The whole horizontal plate is called the cribriform plate that the holes are in.
What is a hole in a bone?
A jawbone cavitation is a hole in the bone that cannot be detected through visual inspection and is poorly detected by radiographs. The term “cavitation” was coined to describe the result of a disease process in which the lack of blood supply to an area of bone resulted in a hole or “hollowed out” portion of the jawbone or other bones in the body.
What is a bone opening?
Internal Acoustic Meatus (Temporal Bone) Opening through which the nerves that carry auditory and orientation information to the brain and that transmit nerve impulses to and from the facial muscles and gland, and parts of the tounge.
