Examples of Tissues in the following topics:
- Connective tissues encompass a diverse array of tissue types that are involved in binding and supporting body structure and tissues.
- 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.
- The two types of adipose tissue are white adipose tissue (WAT) and brown adipose tissue (BAT).
- Bone tissue is also called the osseous tissue.
- Connective tissue (CT) is a one of the four main classes of tissues.
- Although it is the most abundant and widely distributed of the primary tissues, the amount of connective tissue in a particular organ varies.
- Connective tissue fibers provide support.
- Three types of fibers are found in connective tissue:
- They help the connective tissue to stretch and recoil.
- The human body consists of four types of tissue: epithelial, connective, muscular, and nervous.
- Epithelial tissue covers the body, lines all cavities, and composes the glands.
- In its role as an interface tissue, epithelium accomplishes many functions, including:
- Protection for the underlying tissues from radiation, desiccation, toxins, and physical trauma.
- Regulation and excretion of chemicals between the underlying tissues and the body cavity.
- Tissues are groups of similar cells that have a common function.
- The four basic tissue types are epithelial, muscle, connective, and nervous tissue.
- Each tissue type has a characteristic role in the body:
- Most organs contain more than one tissue type.
- Cells form tissues, and tissues form organs.
- The tissues of lymphoid organs are different than the tissues in most other organ systems in that they vary considerably based on cell cycle proliferation of lymphocytes.
- Specialized lymphoid tissue supports proliferation and differentiation of lymphocytes.
- Lymphatic tissue begins to develop by the end of the fifth week of embryonic development.
- Development of lymphatic tissue starts when venous endothelial tissues differentiate into lymphatic endothelial tissues.
- The thymus and bone marrow are primary lymphoid tissue, while the lymph nodes, tonsils, and spleen are secondary lymphoid tissue.
- Collagen is a group of naturally-occurring proteins found in animals, especially in the flesh and connective tissues of mammals.
- Collagen fibrils/aggregates are arranged in different combinations and concentrations in various tissues to provide varying tissue properties.
- Elastic tissue is classified as "connective tissue proper. " The elastic fiber is formed from the elastic microfibril and amorphous elastin.
- Elastic fibers are found in the skin, lungs, arteries, veins, connective tissue proper, elastic cartilage, periodontal ligament, fetal tissue, and other structures.
- This network acts as a supporting mesh in soft tissues such as liver, bone marrow, and the tissues and organs of the lymphatic system.
- In humans, most cells combine to form tissues, but some cells are found independent of solid tissues and have their own functions.
- Humans have four different types of basic tissues.
- Connective tissues such as bone tissue are made up of fibrous cells and give shape and structure to organs.
- Nervous tissue is made of specialized cells that transmit information through electrochemical impulses, such as the tissue of nerves, the spinal cord, and the brain.
- Most organs contain tissues such as parenchyma (used to perform the organ functions), stroma (connective tissue specific to organs) and epithelial.
- Tissue engineering is the synthesis of surgical grade human tissue or tissue analogue via culture or manufacture.
- While most definitions of tissue engineering cover a broad range of applications, in practice the term is closely associated with applications that repair or replace portions of or whole tissues (i.e., bone, cartilage, blood vessels, bladder, skin, etc.).
- Often, the tissues involved require certain mechanical and structural properties for proper functioning.
- One of the continuing, persistent problems with tissue engineering is mass transport limitations.
- A bioreactor in tissue engineering, as opposed to industrial bioreactors, is a device that attempts to simulate a physiological environment in order to promote cell or tissue growth in vivo.
- Transplant or graft rejection occurs when a transplanted tissue is rejected by the recipient's immune system.
- Transplant (or graft) rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue.
- Tissue typing is a procedure in which the tissues of a prospective donor and recipient are tested for compatibility prior to transplantation.
- Different types of transplanted tissues tend to favor different balances of rejection mechanisms.
- Describe the role of tissue typing and graft rejection in transplantation
- Skeletal muscle tissue is composed of numerous
muscle fibers which are separated from adjacent muscles and other tissues by a
layer of dense, elastic connective tissue termed the fascia.
- This fascia can
project beyond the end of the muscle and attach to bones, other muscles, and
- Key muscle groups and the associated vascular and
nervous systems can also be separated from other tissue, such as in the
- Skeletal muscle is surrounded by a thick outer layer of connective tissue termed the fascia.
- Each fascicle is surrounded by another layer of connective tissue termed the endomysium.
