What is the nerve tissue?

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.

Similarly one may ask, what is the main functions of the nervous tissue?

Neural tissue is specialized for the conduction of electrical impulses that convey information or instructions from one region of the body to another. About 98% of neural tissue is concentrated in the brain and spinal cord, which are the control centers for the nervous system.

What is the function of nervous tissue system?

The central nervous system is made up of the spinal cord and brain and is the central processing center for all stimuli. Peripheral nervous tissue consists of nerves made up of nerve cells called neurons. Nerves extend all over the body, from the tips of the fingers to internal organs.

What is the primary function of nerve tissue?

Nervous tissue or nerve tissue is the main tissue component of the two parts of the nervous system; the brain and spinal cord of the central nervous system (CNS), and the branching peripheral nerves of the peripheral nervous system (PNS), which regulates and controls bodily functions and activity.

What is the nervous tissue?

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.

What are the characteristics of the nervous tissue?

Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.

What is the function of the muscle tissue?

There are three types of muscle tissues : skeletal, cardiac and smooth muscles. Muscle tissue provides a) posture and body support b) locomotion and c) heat production. Muscle tissue is examined with respect to function and types of muscle, structure and mechanism of contraction and attachments.

Where is the nervous tissue found in the body?

Nervous tissue is found in peripheral nerves throughout the body and in the organs of the central nervous system, the brain and spinal cord. Nerve tissue is composed of neurons, which are specialized cells able to react to stimuli by sending a signal down a long strand of cell known as an axon.

What are the different types of nervous tissue?

Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.

Are the functional units of the nervous tissue?

Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system.

What is the function of the epithelial tissue?

Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane.

What is the definition of glandular tissue?

The glandular tissue are a mixture of both endocrine (ductless, hormones are secreted into the blood) and exocrine (have ducts, hormones are secreted onto surfaces) glands. The exocrine glands are covered in the respective topics.

What is blood tissue?

Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.

What is an example of a muscle tissue?

Skeletal muscle tissue is found in our skeletal muscles; for example, the biceps. Cardiac muscle is found in our heart, and smooth muscle is found in our visceral, or hollow, organs – for example, blood vessels and intestines. All muscles contract as a result of interaction between special proteins within the myocytes.

Are satellite cells in the CNS or PNS?

In the central nervous system, glia develop from the ventricular zone of the neural tube. These glia include the oligodendrocytes, ependymal cells, and astrocytes. In the peripheral nervous system, glia derive from the neural crest. These PNS glia include Schwann cells in nerves and satellite glial cells in ganglia.

What is the function of the nervous system in the human body?

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

What kind of tissue is a gland?

The correct answer is B. Cuboidal epithelial tissue gives rise to glands in the body. They line the surface of various ducts, glands and organs. This type of tissue is also known as glandular epithelium. For glands to develop, cells in the epithelium increase by mitosis.

What do nerves do in the body?

Nerves are specialised cells – they carry messages from one part of the body to another, as tiny electrical signals. Sensory neurones carry signals from sensory receptors to the spinal cord and brain. Together, the spinal cord and brain make up the central nervous system. Sensory receptors are specialised cells.

What is the function of the connective tissue?

Blood, a fluid connective tissue, provides a transport system within our body for oxygen and other important substances. Cartilage provides strong support and connection for our skeletal framework. And the function of bones is to support and protect soft tissues and organs in our body.

How do nerve cells communicate with each other?

Here is how neurons (nerve cells) communicate: An electrical signal travels down the axon. Chemical neurotransmitter molecules are released into the synapse. The neurotransmitter molecules bind to receptor sites on the releasing neuron and the second neuron.

What are the two types of connective tissue?

Special connective tissue consists of reticular connective tissue, adipose tissue, cartilage, bone, and blood. Other kinds of connective tissues include fibrous, elastic, and lymphoid connective tissues.

What is the muscle tissue?

Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles’ ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. Smooth and cardiac muscle contracts involuntarily, without conscious intervention.

What is tissue in the body?

Human body tissue makes up organs and other body parts. There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart.
