Study Notes

Muscle Tissue

Muscle tissue is highly cellular and well vascularized.
Contains specialized contractile units for movement.

Epithelial Tissue

Disorders in simple columnar epithelium may lead to issues in nutrient absorption and mucus secretion.
Ciliated simple columnar epithelium helps move fertilized eggs in the uterine tubes.
Simple squamous epithelium forms air sac walls in lungs for gas exchange.
Pseudostratified columnar epithelium with goblet cells lines most of the respiratory tract and secretes mucus.

Connective Tissue

Bone (osseous tissue) comprises lacunae, calcium salts, and blood vessels.
Adipose tissue serves primarily for nutrient storage and is the exception in connective tissue characterized by a living cell population.
Fibroblasts are the primary blast cells in connective tissue proper.
Connective tissue features a large amount of extracellular matrix composed of fibers and ground substance.

Tissue Repair

Inflammation results in dilated and permeable capillaries.
The first step in tissue repair is inflammation.
Regeneration and fibrosis are later steps post-inflammation, excluding formation of new stem cells.

Cartilage and Supportive Structures

Chondroblasts within cartilage divide and secrete new matrix.
Smooth muscle in the uterus is essential for labor contractions.
Elastic cartilage maintains the shape of the external ear.

Glandular Epithelium

Endocrine glands, such as the thyroid, secrete hormones directly into the blood.
Exocrine glands can be classified as compound tubuloalveolar, similar to salivary glands.
The Golgi apparatus is crucial for goblet cells and other glandular epithelia in secretion processes.

Other Tissue Characteristics

Edema occurs when areolar tissue absorbs excess fluid.
Stratified epithelia are vital where abrasion protection is needed.
The endothelium is crucial for preventing blood clots along arteries and veins.
Dense microvilli modifications of simple columnar epithelium enhance absorption capabilities in the digestive tract.

Structural Support and Strength

Collagen fibers provide high tensile strength, essential for structures like intervertebral discs.
Reticular fibers form a supportive network but are not as prominent in maintaining shape compared to collagen fibers.

Miscellaneous

Chondrocytes are mature cartilage cells found in lacunae and do not include in areolar connective tissue.
Mesenchymal cells are predominantly found in embryonic connective tissue, playing a role in the formation of various tissue types.
