What cavity houses the eye?

What cavity houses the eye?

The orbit is the bony cavity that contains the eyeball, muscles, nerves, and blood vessels, as well as the structures that produce and drain tears. Each orbit is a pear-shaped structure that is formed by several bones.

What does the cranial cavity House?

brain
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.

What is a cavity in anatomy?

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.

Where is 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).

What is anatomical cavity or compartment?

Anatomical terminology 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’s in the cranial cavity?

The cranial cavity houses the Brain, Meninges, and the Cerebrospinal Fluid. The primary function of the brain is supplying information to the rest of the body and to help it function as whole.

What is the difference between dorsal and posterior?

Anterior (or ventral) Describes the front or direction toward the front of the body. Posterior (or dorsal) Describes the back or direction toward the back of the body.

What composes the dorsal cavity?

The dorsal cavity is the entirety of the back; it consists of the brain stem and the entire spinal cord. It also consists of all the nerve plexuses and single nerves that exit the spinal cord via the spinal column.

What are the 3 layers of the eyes?

Topic Overview

• The outer layer of the eyeball is a tough, white, opaque membrane called the sclera (the white of the eye).
• The middle layer is the choroid.
• The inner layer is the retina, which lines the back two-thirds of the eyeball.

Where is the vitreous located in the eye?

The vitreous cavity lies between the lens and the back of the eye. A jellylike substance called vitreous humor fills the cavity. Light that is focused into the eye by the cornea and lens passes through the vitreous onto the retina — the light-sensitive tissue lining the back of the eye.

Which is part of the eye holds the lens?

Small fibers called zonules are attached to the capsule holding the lens, suspending it from the eye wall. The vitreous cavity lies between the lens and the back of the eye. A jellylike substance called vitreous humor fills the cavity, nourishing the inside of the eye and helping the eye hold its shape.

What are the names of the parts of the eye?

There are many parts of the eye. The anatomy of the eye includes the cornea, pupil, lens, sclera, conjunctiva and more.

Which is part of the eye provides us with central vision?

A tiny but very specialized area of the retina called the macula is responsible for giving us our detailed, central vision. The other part of the retina, the peripheral retina, provides us with our peripheral (side) vision. The retina has special cells called photoreceptors. These cells change light into energy that is transmitted to the brain.
