Study Notes

Introduction to Anatomy

Human anatomy studies the organization of structures in the human body.
Anatomical study methods include regional, systemic, surface, radiographic, sectional, endoscopic, and clinical anatomy.

Levels of Structural Complexity

Anatomy ranges from microscopic (cells) to macroscopic (organs and systems).
Cells and their extracellular components form all body tissues.

Cell Structure

Cellular functions are performed by specialized eukaryotic cells with distinct nuclei and various organelles.
DNA carries genetic instructions, existing as double-helical structures composed of nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G).
RNA aids in protein synthesis; forms include messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
Chromosomes, made of DNA and proteins, carry hereditary information; humans have 23 pairs.
Mitochondria, known as the "powerhouses," produce adenosine triphosphate (ATP) for energy.
The endoplasmic reticulum (ER) synthesizes and transports proteins and lipids, with rough ER containing ribosomes and smooth ER lacking them.
The Golgi apparatus processes and distributes molecules, modifying proteins through glycosylation and sorting them into vesicles for transport.
Lysosomes digest waste and damaged organelles using acidic enzymes, also engaging in autophagy.

Cell Cycle and Mitosis

The cell cycle regulates growth and division in cells, from fertilized egg to multicellular organisms.
Mitosis produces two genetically identical daughter cells, each receiving the full set of 46 chromosomes.
In mitosis, chromosomes replicate and condense, transitioning through stages including prophase.

Tissues and Organ Formation

Four basic types of tissues: epithelial, connective, muscular, and nervous, combine to form organs and systems.
Tissues interact in variable proportions to create the body's distinct structures.

Epithelial Tissue

Functions as protective barriers lining body surfaces and organs.
Examples include:
- Simple Squamous: Thin, flat cells for diffusion (e.g., blood vessels).
- Simple Cuboidal: Cube-shaped cells for secretion/absorption (e.g., kidney tubules).
- Simple Columnar: Elongated cells with microvilli for absorption (e.g., digestive tract).
- Stratified Squamous: Multiple layers for protection (e.g., skin, esophagus).
- Transitional: Specialized for stretching (e.g., urinary bladder).

Connective Tissue

Provides a supportive matrix connecting tissues and organs, with major components including the extracellular matrix (ECM).
Types of specialized connective tissue:
- Adipose Tissue: Fat-storing cells, representing 15%-20% of body weight in men and more in women.
- Cartilage: Flexible tissue with types including hyaline, elastic, and fibrocartilage.
- Bone Tissue: Solid framework of the skeleton, protects organs, stores minerals, and contains marrow for blood cell formation.
- Blood: A liquid matrix (plasma) housing red and white blood cells, essential for transportation and immune function.

Muscle Tissue

Responsible for movement through contraction and relaxation, includes three types:
- Skeletal Muscle: Multinucleated, voluntary muscle with striations, attached to bones for body movement.
- Cardiac Muscle: Involuntary, striated muscle exclusive to the heart, featuring intercalated discs for synchronized contractions.
