Study Notes

Glands and Secretion

Merocrine sweat glands secrete sweat for body cooling.
Apocrine sweat glands produce viscous sweat during stress or sexual arousal.
Sebaceous glands secrete oily substance (sebum) to lubricate the skin and hair.
Ceruminous glands secrete a waxy substance for ear protection.

Wound Healing

The first step in wound healing is blood clot formation.
Leukocytes help clean the wound during granulation tissue formation.

Skin and Cancer

UVB radiation is most responsible for causing damage to skin DNA.
Basal cell carcinoma originates in the stratum basale layer of the skin.
Melanoma is the most dangerous skin cancer due to its tendency to spread.
The papillary layer of the dermis is composed of loose areolar connective tissue.

Skin Structures and Functions

Dermal papillae increase surface area for nutrient exchange.
The epidermis is responsible for producing Vitamin D.
Lanugo is the unpigmented hair found on fetuses.

Epithelial Tissue

The epidermis consists of stratified squamous (keratinized) epithelium.
Carotene contributes to a yellow-orange hue in the skin, derived from diet.

Muscle Tissue

Smooth muscle is found in the walls of hollow organs.
Epithelial tissue is classified based on cell shape and the number of layers.

Connective Tissue

Loose connective tissue (areolar tissue) has large amounts of ground substance and fewer fibers.
Adipose tissue stores energy as fat and cushions organs.
Reticular connective tissue forms the framework of organs like the spleen and lymph nodes.

Cell Junctions

Desmosomes provide mechanical stability by anchoring cells together.
Gap junctions facilitate communication between cells, notably in cardiac muscle tissue.
Tight junctions prevent leakage between epithelial cells.

Cell Structure and Functions

The nucleus stores and protects genetic material (DNA).
Protein synthesis occurs in the ribosomes.
Glycolysis occurs in the cytoplasm, while the mitochondria produce ATP mainly through cellular respiration.

Cell Cycle and Mitosis

DNA replication occurs during the S phase of the cell cycle.
The final step in mitosis is cytokinesis, leading to the division of the cytoplasm.
Chromosomes align in the middle of the cell during metaphase.

Metabolic Processes

The citric acid cycle produces energy carriers like NADH and FADH2.
Glycolysis is an anaerobic process.

Transport Mechanisms

Active transport requires ATP to move substances across the cell membrane.
Osmosis is the transport of water across a selectively permeable membrane.
Endocytosis involves the engulfing of substances into the cell, while receptor-mediated endocytosis involves specific uptake through receptors.

Cellular Components

The Golgi apparatus modifies and packages proteins for secretion.
Fibroblasts in connective tissue produce collagen and other fibers.
Melanin, produced by melanocytes, provides protection against UV damage.
The stratum corneum contains the most layers of dead keratinized cells.
