Where is the central 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 are the two main body cavities?
Body Cavities The cavities, or spaces, of the body contain the internal organs, or viscera. The two main cavities are called the ventral and dorsal cavities. The ventral is the larger cavity and is subdivided into two parts (thoracic and abdominopelvic cavities) by the diaphragm, a dome-shaped respiratory muscle.
What organs are in the cranial cavity?
Cranial. The cranial cavity is the anterior portion of the dorsal cavity consisting of the space inside the skull. This cavity contains the brain, the meninges of the brain, and cerebrospinal fluid.
How many types of cavities are there?
The three types of cavities are shown here. Smooth surface cavities occur on the smooth sides of your teeth, while root cavities develop on the surface over the roots. Pit and fissure cavities occur on the chewing surface of your teeth.
What is in medullary cavity?
The medullary cavity is the hollow part of bone that contains bone marrow. The bone marrow makes blood cells and stores fat. Spongy bone (also called cancellous bone) is made up of small, needle-like pieces of bone arranged like a honeycomb.
Where is the diaphysis?
The central tubular region of the bone, called the diaphysis, flares outward near the end to form the metaphysis, which contains a largely cancellous, or spongy, interior. At the end of the bone is the epiphysis, which in young people is separated from the metaphysis by the physis, or growth plate.
What cavity is the brain in?
cranial cavity
The cranial cavity fills most of the upper part of the skull and contains the brain. The spinal cavity is a very long, narrow cavity inside the vertebral column. It runs the length of the trunk and contains the spinal cord.
Which body cavity contains the peritoneum?
the abdominal cavity
The peritoneum is the serous membrane that lines the abdominal cavity. It is composed of mesothelial cells that are supported by a thin layer of fibrous tissue and is embryologically derived from the mesoderm.
What cavity is the spleen in?
left abdominal cavity
The spleen is located in the upper left abdominal cavity, just beneath the diaphragm, and posterior to the stomach. It is similar to a lymph node in shape and structure but it is much larger. The spleen is the largest lymphatic organ in the body.
What is yellow marrow?
There are two types of bone marrow: red and yellow. Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow bone marrow is made mostly of fat and contains stem cells that can become cartilage, fat, or bone cells.
What does a central cavity do?
Thoracic cavity, the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity by the diaphragm. Among the major organs contained in the thoracic cavity are the heart and lungs.
What is the function of central cavity?
Small-intestinal mesentery. This region is connected to your small intestine,specifically the jejunum and ileum regions.
What cavity contains the central nervous system?
This swelling condition is called hydrocephalus (“water head”) and can cause seizures, cognitive problems, and even death if a shunt is not inserted to remove the fluid and pressure. The brain is the part of the central nervous system that is contained in the cranial cavity of the skull.
What cavities are located in the ventral cavity?
The ventral cavity includes the thoracic and abdominopelvic cavities and their subdivisions. The dorsal cavity includes the cranial and spinal cavities. Similarly, what protects the ventral cavity? The walls of the ventral body cavity and outer covering of its organs contain a thin covering called the serosa (also called serous membrane).
