Study Notes
Nervous Tissue
- Composed of neurons and neuroglial cells
- Neurons initiate and transmit electrical signals
- Neuroglial cells support and protect neurons
Muscle Tissue
- Skeletal muscle: Attached to bones, responsible for voluntary movement and thermoregulation. Long, cylindrical, multinucleated fibers with visible striations.
- Cardiac muscle: Found in the heart, responsible for pumping blood. Medium-sized, branching cells with one or two centrally located nuclei and intercalated discs (under involuntary control).
- Smooth muscle: Located in internal organs, responsible for involuntary movement (e.g., intestines, stomach). Short fusiform cells with a centrally located nucleus, lack visible striations (under involuntary control).
Epithelial Tissue
- Lines and covers surfaces, and forms glands
- Cells are tightly packed to create a barrier with no extracellular matrix.
- Classified by cell layers (simple or stratified) and cell shape (squamous, cuboidal, columnar, pseudostratified) Example shapes: simple squamous, stratified squamous, simple columnar, keratinized stratified squamous, pseudostratified columnar.
Connective Tissue
- Supports and connects other tissues & organs.
- Characterized by an extracellular matrix between cells
- Fluid Connective Tissue: Blood (red blood cells, white blood cells, platelets)
- Supporting Connective Tissue: Cartilage (hyaline, fibro, elastic) and Bone (osteoblasts, osteocytes, osteoclasts)
- Connective Tissue Proper: Loose connective tissue (areolar, adipose, reticular) and Dense connective tissue (dense regular, dense irregular, elastic)
- Loose connective tissue: A body packing material, surrounds organs.
- Areolar: Abundant, viscous ground substance, few collagen and elastic fibers, primarily protects and binds
- Adipose: Closely packed adipocytes, stores energy, insulates, cushions.
- Reticular: Meshwork of reticular fibers; stroma for lymphatic organs.
- Dense connective tissue: Provides strength;
- Dense irregular: Irregularly arranged collagen fibers, withstands stress in all directions (superficial layers of dermis, organ capsules)
- Dense regular: Parallel collagen fibers, withstands stress in one direction (tendons, ligaments)
- Elastic: Elastic fibers, allows for stretching and recoil (walls of large arteries, vocal cords, ligaments).
- Loose connective tissue: A body packing material, surrounds organs.
