Study Notes

Adipose Tissue

Primary function is nutrient storage.
Functions to hold organs like kidneys in place.
Contains "blast" cells that are undifferentiated and actively dividing.

Epithelial Tissue Modifications

Dense microvilli enhance absorption in simple columnar epithelium.
Pseudostratified columnar epithelium appears layered but all cells contact the basement membrane.
Ciliated simple columnar epithelium aids in moving fertilized eggs in uterine tubes.
Simple squamous epithelium forms walls of air sacs for gas exchange in lungs.

Connective Tissue Characteristics

Composed of ground substance, fibers, and cells; types include adipose, bone, and areolar.
Contains collagen fibers, providing high tensile strength and flexibility.
Chondroblasts are responsible for matrix secretion in cartilage.
Contains elastic fibers found in skin, lungs, and blood vessel walls.

Cartilage Types

Hyaline cartilage provides support and flexibility.
Elastic cartilage maintains shape, as seen in external ear.
Fibrocartilage contains collagen fibers, giving intervertebral discs their tensile strength.

Muscle Tissue

Muscle tissue is highly cellular and vascularized, including smooth muscle in the uterus for contractions.
Skeletal muscle consists of many cells joining together, contributing nuclei.
Heart muscle cells are connected by intercalated discs, preventing separation.

Gland Types

Exocrine glands, such as compound tubuloalveolar glands, secrete products through ducts.
Endocrine glands, such as the thyroid, release hormones directly into the blood.

Tissue Repair Processes

Inflammation is the first step in tissue repair, leading to capillary dilation.
Edema occurs when areolar tissue absorbs excess fluid during inflammation.
New stem cell formation is not considered a step in tissue repair.

Miscellaneous Facts

Connective tissue extracellular matrix is largely non-living, with adipose being an exception.
Arteries and veins prevent clot formation due to health of their endothelium.
Goblet cells are present in simple columnar epithelial tissue, secreting mucus.

Miscellaneous Cell Characteristics

Lacunae, calcium salts, and blood vessels are features of bone (osseous tissue).
The Golgi apparatus is crucial for the function of glandular epithelial cells, like goblet cells.
Fixing a sample with preservative is the first step in examining unknown organs under microscopy.
