Study Notes
Types of Tissues
-
Epithelium
- Forms mucous, serous, and epidermal membranes.
- Cells can absorb and/or secrete substances.
- Found in structures like the lining of the stomach and small intestine (simple columnar) and skin epidermis (stratified squamous).
- Often characterized by cell layering, such as pseudostratified columnar which lines the respiratory tract.
-
Muscle
- Allows for organ movements; involved in voluntary actions (e.g., skeletal muscle) and involuntary actions (e.g., cardiac and smooth muscle).
- Cells shorten to exert force, crucial for physical activities like smiling and swimming.
- Three types:
- Skeletal muscle is multinucleate, voluntary, and found attached to bones.
- Cardiac muscle is involuntary, striated, contains intercalated discs, and forms the heart tissue.
- Smooth muscle is found in walls of organs like the stomach and arteries, involuntary, and consists of spindle-shaped cells.
-
Nervous Tissue
- Transmits electrochemical impulses, forming the basis of the body’s major controlling system.
- Composed of neurons and supportive cells, forming the brain and spinal cord.
-
Connective Tissue
- Supports and binds other tissues; characterized by a large nonliving matrix.
- Types include:
- Dense fibrous connective tissue, which provides strength through parallel collagen fibers (found in tendons and the dermis).
- Adipose connective tissue, acts as a fat storage depot and provides insulation.
- Osseous tissue, which forms the bony skeleton and has a hard matrix due to calcium salts.
- Hyaline cartilage, which forms the embryonic skeleton and reinforces structures such as the trachea.
- Reticular connective tissue, which forms the internal structure of lymphoid organs like lymph nodes and the spleen.
Specific Tissue Characteristics
-
Cardiac Muscle
- Displays cylindrical cells with branching ends and possesses intercalated discs.
- Responsible for the pumping action of the circulatory system.
-
Skeletal Muscle
- Contains long, non-branching cylindrical cells, voluntarily controlled, and is essential for locomotion of the body.
-
Smooth Muscle
- Contains spindle-shaped cells, changes the internal volume of organs during contraction, involuntarily controlled.
-
Epithelial Variants
- Stratified squamous: Best suited for areas subjected to friction, like the esophagus.
- Simple squamous: Forms thin serous membranes, consisting of a single layer of flattened cells.
Functional Roles
- Epithelium forms protective barriers and aids in secretion.
- Muscle tissue enables dynamic movement and force application.
- Nervous tissue coordinates activity through electrochemical signaling.
- Connective tissue provides structural support, protection, and nourishment for various organs.
