The cranium is made up of cranial bones (bones that surround and protect the brain) and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face). An opening at the base of the cranium is where the spinal cord connects to the brain.

What is spinal cavity?

The vertebral canal, otherwise known as the vertebral cavity or spinal cavity, is an anatomical space formed by the vertebral column that stores an integral portion of the central nervous system: the spinal cord and the spinal nerve roots branching off the spinal cord bilaterally.

What is cavities of the body?

A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity.

What are the names of the two main cavities of the body?

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 is between brain and skull?

Between the skull and brain is the meninges, which consist of three layers of tissue that cover and protect the brain and spinal cord. From the outermost layer inward they are: the dura mater, arachnoid and pia mater. … Arachnoid: The second layer of the meninges is the arachnoid.

What is the cranial nerve?

What are cranial nerves? Your cranial nerves are pairs of nerves that connect your brain to different parts of your head, neck, and trunk. There are 12 of them, each named for their function or structure. Each nerve also has a corresponding Roman numeral between I and XII.

What keeps the brain in place?

meninges The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.

The abdominal cavity contains digestive organs, the pelvic cavity contains the urinary bladder, internal reproductive organs, and rectum. There are two methods for dividing the abdominopelvic cavity.

Which cavity is the intestines in?

abdominal cavity The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. It contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, and most of the small and large intestines. It also contains the urinary bladder and internal reproductive organs.

What is in the dorsal cavity?

The dorsal cavity lies close to the spine in the posterior portion of the body. The dorsal cavity contains the spinal column, central nervous system (i.e., brain and spinal cord), and meninges (i.e., tissue that surrounds the brain and spinal cord).

Where is the cranial region?

The cephalic region (head) or cranial region (skull) is at the top of the body and visible from the front and rear. The cervical region (neck) starts below the head, ends at the thorax, and is visible from the front and rear from below the head to the shoulders.

What is cranial anatomy?

Cranium. The eight bones that protect the brain are called the cranium. The front bone forms the forehead. Two parietal bones form the upper sides of the skull, while two temporal bones form the lower sides.

What is the function of spinal cavity?

The main purpose of the spinal cavity is similar to that of the cranial cavity. The spinal cord is extremely sensitize to damage and must be cushioned. Further, the separation provides some protection from exposure to bacteria and viruses.

What is cavity of spinal canal?

The spinal cavity (or vertebral cavity or spinal canal) is the cavity that contains the spinal cord within the vertebral column, formed by the vertebrae through which the spinal cord passes. It is a process of the dorsal body cavity. This canal is enclosed within the vertebral foramen of the vertebrae.

What are the four main body cavities?

Humans have four body cavities: (1) the dorsal body cavity that encloses the brain and spinal cord; (2) the thoracic cavity that encloses the heart and lungs; (3) the abdominal cavity that encloses most of the digestive organs and kidneys; and (4) the pelvic cavity that encloses the bladder and reproductive organs.
