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.
