Study Notes

Introduction to Anatomy

Anatomy is the branch of science concerned with the structure of organisms and their parts.
It encompasses the study of the form and arrangement of body parts, from the smallest cellular components to the largest organ systems.
Anatomical studies utilize various techniques, including dissection, imaging, and microscopy.

Branches of Anatomy

Gross Anatomy: Examines large structures and visible features of the body, such as organs and organ systems.
Microscopic Anatomy: Investigates structures that require magnification to visualize, such as cells and tissues.
Developmental Anatomy: Studies the structural changes in organisms through their lifespan from conception to maturity.
Regional Anatomy: Focuses on the organization of structures within a specific region of the body.
Systemic Anatomy: Explores the structure of a specific body system, like the nervous or cardiovascular system.

Anatomical Terminology

Anatomical position: A standardized reference point for describing body locations and directions, with the body erect, facing forward, arms at the sides, palms forward.
Directional terms: Used to describe the location of one body part relative to another (e.g., superior, inferior, anterior, posterior, medial, lateral, proximal, distal).
Body planes: Imaginary flat surfaces used to dissect the body into sections (e.g., sagittal, coronal, transverse).

Body Cavities

Dorsal body cavity: Houses the brain and spinal cord.
Ventral body cavity: Contains the organs of the respiratory, digestive, cardiovascular, and other systems and is divided into the thoracic and abdominopelvic cavities.
- Thoracic cavity (chest): Contains the heart and lungs.
- Abdominopelvic cavity (abdomen and pelvis): Houses organs like the stomach, intestines, liver, and reproductive organs.

Body Systems

Integumentary system: Protection, temperature regulation, and sensation.
Skeletal system: Support, protection, movement, and blood cell formation.
Muscular system: Movement, posture, and heat production.
Nervous system: Control and coordination of body functions.
Endocrine system: Hormones that regulate various processes.
Cardiovascular system: Circulation of blood.
Lymphatic system: Immunity and fluid balance.
Respiratory system: Gas exchange.
Digestive system: Food digestion and absorption.
Urinary system: Waste removal and fluid balance.
Reproductive system: Reproduction.

Histology

Histology is the study of tissues.
Tissues are groups of cells with similar structure and function.
There are four primary tissue types: epithelial, connective, muscular, and nervous.
Each tissue type has specific properties and functions that contribute to the overall functioning of the organism.

Cell Structure

Cells are the basic units of life.
Cells contain various organelles that carry out specific functions.
The structure of a cell relates to its function.
Cells have a plasma membrane to control what enters and exits the cell.
Cells have internal components such as the nucleus (controlling center), mitochondria (powerhouses), and endoplasmic reticulum (involved in protein synthesis).

Imaging Techniques in Anatomy

X-rays: Detect bone density and fractures.
CT scans (Computed Tomography): Create cross-sectional images of the body.
MRIs (Magnetic Resonance Imaging): Produce detailed images of soft tissues.
Ultrasound: Use sound waves to create images of internal structures.
