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.
