SPECIALIZED CELLS AND TISSUE

TISSUE TYPES

• The cells that come together to make tissue all have a somewhat similar structure and act in the same way.
• Epithelial, connective, muscular, and nerve tissue are the four primary forms of tissue, each of which originates from a distinct cell layer in the early embryo.
• Connective tissues include blood, bone, cartilage, tendons, and ligaments among other things.
• There are many different types of epithelial tissues, including the epidermis and the tissues that line practically every organ.
• Naturally, muscles and nerves are composed of muscle and nerve tissues, respectively.

White matter

• Contains a lengthy nerve that is wire-like and insulated.

Gray matter

• Contains both the bodies of nerve cells and support cells.

Nerve tissue

• An view of nerve tissue taken using a microscope, displaying the glial cells that are there to support the nerve cells (neurons).
• The creatures that resemble spiders provide the nourishment.

Elastic cartilage

• Light and pliable; holds

Hyaline cartilage

• Tough yet flexible; The most common

Elastic cartilage

• Chondrocytes, which are spherical cells, can be seen in a sample of cartilage taken from the epiglottis.
• These cells are embedded in fibers of elastin, which give the cartilage its lightness and flexibility.

Loose connective tissue

• A portion of the connective tissue in the body is made up of cells that are only loosely encased in the fibers.
• The nuclei of fibroblast cells can be observed here as black dots.

Connective dermal tissue

• Connects dermis of skin to underlying organs

Skeletal muscle tissue

• Connective tissue that is white in color surrounds each bundle of contractive filaments, which can be seen here in the form of stripes.
• The nuclei are represented by the dark patches.

Dense connective tissue

• This sturdy and dense tissue is present in the lower layer of the epidermis, as well as in the ligaments and tendons (dermis).

Dermis

• Lower layer of skin

Sweat gland

• Part of epithelial tissue Of skin

Adipose tissue

• Adipocytes are cells that are found surrounding internal organs and under the skin, and they are responsible for the formation of a fatty connective tissue known as adipose.

Fat tissue

• Beneath dermis layer Of skin

Smooth muscle tissue

• Smooth muscular tissue is characterized by its long fibers, which are responsible for involuntary contractions.
• They are located in a variety of tubular internal organs, such as the intestine, for example.

Spongy bone tissue

• Spongy bone has a honeycomb-like structure that is both lightweight and strong, and it is in these huge open areas where bone marrow may be found.

Blood

• Blood is a fluid connective tissue found throughout the body.
• It is composed of platelets, which are pieces of cells, as well as liquid plasma, which contains red and white blood cells.
