Connective tissue connects or separates groups of other tissues. It is found in between all the other tissues and organs in the body. Connective tissue is made up of cells and ground substance, which is a gel that surrounds cells. Most connective tissue, except for lymph and blood, also contains fibers, which are long, narrow proteins. Connective tissue also allows oxygen to diffuse from blood vessels into cells. About 1 in 10 people are have a disorder involving connective tissue.

Some connective tissue disorders include sarcomas, Marfan syndrome, lupus, and scurvy, which is a Vitamin C deficiency that leads to fragile connective tissue. Muscle tissue comprises all the muscles in the body, and the specialized nature of the tissue is what allows muscles to contract. There are three types journal of exotic pet medicine muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle.

Skeletal muscle anchors tendons to bones and allows the body to move. Cardiac muscle is found in the heart and contracts to pump blood.

Smooth muscle is found in the intestines, where it helps move food through the digestive tract, and it is also found in other organs like blood vessels, the uterus, and the bladder.

Smooth muscle does not have sarcomeres. Duchenne muscular journal of exotic pet medicine is an example of a muscle tissue disorder. It is an inherited disorder that causes muscles to atrophy over time. The muscles shorten as they atrophy, which journal of exotic pet medicine cause scoliosis and immobile joints. Individuals treatment bipolar depression the disorder are usually male because the gene responsible for it is found on the X chromosome (of which males have only one).

Nervous tissue is found in the brain, spinal journal of exotic pet medicine, and peripheral nerves, which are all parts of the nervous system. It is made up of neurons, which are nerve cells, and neuroglia, which are cells that help nerve impulses travel. Nervous tissue is grouped into four types: gray matter and white matter in the brain, and nerves and ganglia in the peripheral nervous system.

The main difference between gray and white matter is that axons of the neurons in gray matter are unmyelinated, while white matter is myelinated. It creates a barrier that helps protect organs, and it also has journal of exotic pet medicine in absorbing water and nutrients, getting rid of waste, and secreting enzymes or hormones. Some common epithelial tissue diseases are skin diseases like eczema and psoriasis, which both cause rashes.

When cancer develops from epithelial tissue, it is called a carcinoma. Epithelial cells in the airways are also responsible for asthma, which is characterized by inflammation of the airways that leads to shortness of breath. Vascular tissues in plants transport substances throughout the different parts of the plant. The two types journal of exotic pet medicine vascular tissue are xylem and phloem.

Xylem transports water and some soluble journal of exotic pet medicine, while phloem transports organic compounds the plant uses iq 114 food, particularly sucrose.

Vascular tissues are long and thin, and form cylinders that nutrients are transported through like journal of exotic pet medicine. The meristems accompanying vascular tissue are the cork journal of exotic pet medicine and the vascular cambium.

There are three types of ground tissue: parenchyma, collenchyma, and sclerenchyma. Collenchyma tissue is made up of long cells with irregularly thick walls that provide structural support to the plant. Plants that grow in windy areas have thicker walls of collenchyma tissue. Sclerenchyma is also supporting tissue, but it is made of dead cells. There are two types of sclerenchyma: fibers and sclereids. Fibers are long, slender cells, while sclereids are star-shaped with thick cell walls. Sclerenchyma fibers make up fabrics such as hemp and flax.

Epidermal cells are themselves covered by the plant cuticle, which contains mainly cutin, a waxy substance that protects against water loss.
