Study Notes
Blood (Vascular Tissue)
- Composed of blood cells suspended in liquid matrix called blood plasma.
- Soluble fibers visible only during clotting.
- Functions to transport nutrients, wastes, and respiratory gases.
- Found in blood vessels.
- Key cell types: Red Blood Cells (RBC), White Blood Cells (WBC), and platelets.
Areolar Connective Tissue
- Most widespread connective tissue.
- Soft, pliable texture resembling "cobwebs."
- Serves as universal packing material and holds organs in place.
- Contains a layer known as lamina propria beneath the epidermis, supporting all skin membranes.
- Features a loose network of all fiber types and can absorb excess fluid, causing edema.
Reticular Connective Tissue
- Characterized by a delicate network of interwoven reticular fibers with reticular cells.
- Functions to form stroma, providing structural support to organs.
- Located in lymph nodes, spleen, and bone marrow.
Bone (Osseous Tissue)
- Comprises osteocytes (bone cells) located in lacunae.
- Features a hard matrix of calcium salts and a high content of collagen fibers.
- Functions to protect and support the body.
- Found in all bones, with key features: lacunae, lamellae, and canaliculi.
Nervous Tissue
- Functions to receive and conduct electrochemical impulses throughout the body.
- Key properties: irritability and conductivity.
- Composed of neurons and neuroglia, with neuroglia serving protective and supportive roles for neurons.
- Located in the brain, spinal cord, and nerves.
Hyaline Cartilage
- Most common type of cartilage with hidden abundant collagen fibers in a glassy matrix.
- Functions to aid smooth movement of bones at joints.
- Found in trachea, at the juncture of ribs with the breastbone, and at the ends of long bones.
- Major component of the fetal skeleton and located in growth plates of long bones.
Fibrocartilage
- Highly compressible, acting as a cushion within joints.
- Functions to manage compression forces and reduce stress.
- Found in intervertebral discs of the spinal column and areas needing heavy cushioning.
Simple Squamous Epithelium
- Single layer of flattened cells with disc-shaped nuclei.
- Functions in filtration and diffusion of materials.
- Present in kidney glomeruli, alveoli, heart lining, and serosa.
Simple Cuboidal Epithelium
- Single layer of cube-shaped cells with large spherical nuclei.
- Functions in secretion and absorption.
- Located in kidney tubules, ducts, and the surface of ovaries.
Simple Columnar Epithelium
- Single layer of taller cells with round to oval nuclei, some may have cilia.
- Functions in the secretion of mucus; ciliated type propels mucus.
- Non-ciliated type found from stomach to anal canal; ciliated type found in bronchi and uterine tubes.
Pseudostratified Columnar Epithelium
- Single layer of cells differing in height, containing goblet cells and cilia.
- Functions in mucus secretion and propulsion via ciliary action.
- Non-ciliated type located in male's sperm-carrying ducts; ciliated type found in trachea and bronchi.
Stratified Squamous Epithelium (Keratinized)
- Thick membrane of several layers, with basal cells being cuboidal or columnar and surface cells flattened.
- Functions to waterproof and reduce evaporation from underlying tissues.
- Key component of the epidermis and external skin, with non-keratinized versions found in the vagina.
