the parietal lobe, which controls somatic or voluntary sensory functions; the occipital lobe, which controls vision; the temporal lobe, which controls hearing and some other speech functions.

Where is the nervous system located in the body?

The nervous system has two parts, called the central nervous system and the peripheral nervous system due to their location in the body. The central nervous system (CNS) includes the nerves in the brain and spinal cord. It is safely contained within the skull and vertebral canal of the spine.

Can you live without eyes?

You don't need eyes to survive
Some people may lose an eye due to an injury or have one removed because of cancer. In rare cases, a person could be born without them. While a lack of eyes can create many challenges for a person, they technically aren't a vital organ for survival.

Is the eye an organ?

The human eye is an organ that reacts to light and allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The eye is part of the sensory nervous system.

What is the main purpose of the eye?

Eyes are organs of the visual system. They provide animals with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and convert it into electro-chemical impulses in neurons.

What organs are affected by blindness?

The following eye diseases and conditions can cause blindness:
  • Glaucoma refers to different eye conditions that can damage your optic nerve, which carries visual information from your eyes to your brain.
  • Macular degeneration destroys the part of your eye that enables you to see details.
  • Cataracts cause cloudy vision.

What is the purpose of the eye?


Both are located in the front part of the eye, in front of the lens). The eye receives oxygen through the aqueous. Its function is to nourish the cornea, iris, and lens by carrying nutrients, it removes waste products excreted from the lens, and maintain intraocular pressure and thus maintains the shape of the eye.

What is an eye doctor called?

An ophthalmologist — Eye M.D. — is a medical or osteopathic doctor who specializes in eye and vision care. Ophthalmologists differ from optometrists and opticians in their levels of training and in what they can diagnose and treat.

What color are nerves in the body?

The long processes of a nerve cell are called axons or nerve fibers. The interior of the central nervous system is organized into gray and white matter. Gray matter consists of nerve cells embedded in neuroglia; it has a gray color.

What are the parts of the eyes?

  • Parts of the Eye. Here I will briefly describe various parts of the eye:
  • Sclera. The sclera is the white of the eye.
  • The Cornea. The cornea is the clear bulging surface in front of the eye.
  • Anterior & Posterior Chambers. The anterior chamber is between the cornea and the iris.
  • Iris/Pupil.
  • Lens.
  • Vitreous Humor.
  • Retina.

What part of the brain controls the nervous system?

The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.

How does the sympathetic nervous system affect the eyes?


Stimulation of the autonomic nervous system's sympathetic branch, known for triggering "fight or flight" responses when the body is under stress, induces pupil dilation. Whereas stimulation of the parasympathetic system, known for "rest and digest" functions, causes constriction.

Where is the central nervous system in the brain?

The CNS is contained within the dorsal body cavity, with the brain housed in the cranial cavity and the spinal cord in the spinal canal.

What controls the nervous system?

What does the nervous system do? The nervous system is responsible for: Intelligence, learning and memory: your thoughts and feelings are controlled by the brain, the control centre of the nervous system. Movement: the brain sends messages that control how your body moves.

How the nervous system works?

How Does the Nervous System Work? The basic workings of the nervous system depend a lot on tiny cells called neurons. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body.

What makes up the central nervous system?

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What is our nervous system?


The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.

How important is the nervous system?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

How does the nervous system affect behavior?

The central nervous system has a fundamental role in the control of behavior. It contains the brain and the spinal cord which are both encased in bone which shows their importance. Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.
