Where is Areolar tissue found and what is its function?

Areolar tissue is the most widely distributed connective tissue in the animal body. Located in the skin, areolar tissue binds the outer layers of the skin to the muscles lying underneath. They are also found in, around the mucous membranes, surrounding nerves, blood vessels and various other body organs.

What are the main functions of Areolar connective tissue?

Areolar Connective Tissue These tissues are widely distributed and serve as a universal packing material between other tissues. The functions of areolar connective tissue include the support and binding of other tissues. It also helps in defending against infection.

What is Areolar connective tissue made of?

Areolar connective tissue is made of cells and extracellular matrix (“extra-” means “outside”, so the extracellular matrix is material that is outside of the cells). The matrix has two components, fibers and ground substance.

What are Areolar tissues?

noun, plural: areolar tissues. A connective tissue in which fibers are loosely arranged in a net or meshwork. Supplement. The tissue consists of collagenous and elastic fibers, ground substance, and connective tissue cells.

What is another name for Areolar tissue?

connective tissue

What are the three functions of Areolar tissue?

Acts as a binding tissue. Bind the skin with muscles. Bind the blood vessels and nerves with other structures of body. Helps in healing of wounds.

Where does Areolar tissue occur?

The areolar tissue is a loose connective tissue that can be seen between the skin and muscles; in the bone marrow as well as around the blood vessels and nerves. The areolar tissue fills the spaces between the different organs and connects the skin to the underlying muscles.

What are the characteristics of Areolar connective tissue?

Characteristics. Loose connective tissue (LCT), also called areolar tissue, belongs to the category of connective tissue proper. Its cellular content is highly abundant and varied. The ECM is composed of a moderate amount of ground substance and two main types of protein fibers: elastic and reticular fibers.

a)Areolar: They are found between skin and muscles, around blood vessels, nerves, fill space inside organs. 1)It act as supporting and packing tissue between organs lying in body cavity. 2)it helps in repair of tissue after an injury. 3)It fixes skin to underlying muscles.

Examples of connective tissues include tendons, ligaments, bones, blood, adipose and areolar tissues. Further, there are three types of connective tissues.

What are the fluid connective tissue class 9?

Fluid connective tissue is a connective tiisue in which the matrix is liquid. Examples of this tissue are blood and lymph.

What is connective tissue give two examples?

Specialized connective tissues include a number of different tissues with specialized cells and unique ground substances. Some of these tissues are solid and strong, while others are fluid and flexible. Examples include adipose, cartilage, bone, blood, and lymph.

What is nervous tissue class 9?

Nervous or the nerve tissue is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons.

What is the name of fluid connective tissue?

Fluid Connective Tissue Blood and lymph are fluid connective tissues. Cells circulate in a liquid extracellular matrix. The formed elements circulating in blood are all derived from hematopoietic stem cells located in bone marrow (Figure 6).

What are the two types of fluid connective tissue?

Fluid Connective Tissue Blood and lymph are fluid connective tissues. Cells circulate in a liquid extracellular matrix.

Is nervous tissue a connective tissue?

The word “neuroglia” means “nerve glue.” These cells are nonconductive and provide a support system for the neurons. They are a special type of “connective tissue” for the nervous system.

What is the main function of nerve tissue?

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.

How does the nerve tissue cause action?

When a nerve impulse reaches the muscle the muscle fibre must move. The muscle cells will move by changing their shape so that they shorten. Muscle cells have special proteins that change both their shape and their arrangement in the cell in response to nervous electrical impulses.

What are the characteristics of nerve 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 Colour are nerves?



Axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.

What is a bundle of nerve fibers called?

Structure of a Nerve Mixed nerves contain both types of fibers. A connective tissue sheath called the epineurium surrounds each nerve. Each bundle of nerve fibers is called a fasciculus and is surrounded by a layer of connective tissue called the perineurium.

What are the three types of nerve fibers?

Nerve fibers are classed into three types ” group A nerve fibers, group B nerve fibers, and group C nerve fibers. Groups A and B are myelinated, and group C are unmyelinated.

What happens when a nerve Fibre is stimulated?

When a nerve cell is stimulated, ion channels in the plasma membrane open and Na+ instantly diffuses down its concentration gradient into the cell. These cations override the negative charges in the intracellular fluid, so the inside of the membrane briefly becomes positive.
