Overview of Anatomy

Anatomy is the branch of biology that studies the structure of organisms and their parts.
It can be divided into:
- Gross Anatomy: Study of structures that can be seen with the naked eye (e.g., organs, systems).
- Microscopic Anatomy: Study of structures at the cellular and tissue levels (e.g., histology).

Major Systems of the Body

Skeletal System
- Composed of bones, cartilage, ligaments.
- Functions: Support, protection, movement, mineral storage, blood cell production.
Muscular System
- Composed of skeletal, cardiac, and smooth muscles.
- Functions: Movement, posture, heat production.
Nervous System
- Composed of the brain, spinal cord, and nerves.
- Functions: Control of body activities, processing sensory information, coordination.
Circulatory System
- Composed of the heart, blood vessels, blood.
- Functions: Transport of nutrients, gases, hormones, waste products.
Respiratory System
- Composed of lungs, trachea, and other airways.
- Functions: Gas exchange, oxygen supply, carbon dioxide removal.
Digestive System
- Composed of the gastrointestinal tract and accessory organs (e.g., liver, pancreas).
- Functions: Breakdown of food, nutrient absorption, waste elimination.
Endocrine System
- Composed of glands that secrete hormones (e.g., thyroid, adrenal).
- Functions: Regulation of metabolic processes, growth, and development.
Urinary System
- Composed of kidneys, ureters, bladder, urethra.
- Functions: Waste elimination, regulation of blood volume and pressure, electrolyte balance.
Reproductive System
- Male: testes, penis, associated glands.
- Female: ovaries, uterus, vagina.
- Functions: Production of gametes, hormone regulation, reproduction.
Integumentary System
- Composed of skin, hair, nails.
- Functions: Protection, temperature regulation, sensation.

Anatomical Terminology

Anatomical Position: Standard position where the body is standing upright, facing forward, arms at sides, palms facing forward.
Planes of the Body:
- Sagittal Plane: Divides the body into left and right.
- Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back).
- Transverse Plane: Divides the body into superior (upper) and inferior (lower) parts.

Common Anatomical Terms

Superior vs. Inferior: Above vs. below.
Anterior vs. Posterior: Front vs. back.
Medial vs. Lateral: Closer to the midline vs. farther from the midline.
Proximal vs. Distal: Closer to the trunk vs. farther from the trunk.

Tissues

Epithelial Tissue: Covers body surfaces, lines cavities, forms glands.
Connective Tissue: Supports, binds, and protects other tissues (e.g., bone, blood).
Muscle Tissue: Responsible for movement (skeletal, cardiac, smooth).
Nervous Tissue: Transmits impulses, processes information (neurons, glial cells).

Importance of Anatomy

Fundamental for understanding physiology and medicine.
Provides a basis for clinical practices, surgical procedures, and medical diagnoses.

Overview of Anatomy

Anatomy studies the structure of organisms and their components.
Divided into Gross Anatomy (visible structures) and Microscopic Anatomy (cellular and tissue structures).

Major Systems of the Body

Skeletal System:
- Comprises bones, cartilage, and ligaments.
- Functions include support, protection, movement, mineral storage, and blood cell production.
Muscular System:
- Includes skeletal, cardiac, and smooth muscles.
- Responsible for movement, maintaining posture, and generating heat.
Nervous System:
- Consists of the brain, spinal cord, and nerves.
- Controls body activities, processes sensory information, and coordinates bodily functions.
Circulatory System:
- Encompasses the heart, blood vessels, and blood.
- Transports nutrients, gases, hormones, and waste products throughout the body.
Respiratory System:
- Made up of the lungs, trachea, and airway passages.
- Facilitates gas exchange by providing oxygen and removing carbon dioxide.
Digestive System:
- Composed of the gastrointestinal tract and accessory organs (liver, pancreas).
- Breaks down food, absorbs nutrients, and eliminates waste.
Endocrine System:
- Consists of hormone-secreting glands (thyroid, adrenal).
- Regulates metabolism, growth, and developmental processes.
Urinary System:
- Involves the kidneys, ureters, bladder, and urethra.
- Responsible for waste elimination, blood volume and pressure regulation, and electrolyte balance.
Reproductive System:
- Male includes testes and penis; female includes ovaries and uterus.
- Functions in gamete production, hormone regulation, and reproduction.
Integumentary System:
- Comprises skin, hair, and nails.
- Provides protection, regulates temperature, and enables sensation.

Anatomical Terminology

Anatomical Position: Standard position (standing upright, facing forward, arms at sides, palms forward).
Planes of the Body:
- Sagittal Plane: Divides body into left and right halves.
- Frontal (Coronal) Plane: Divides body into anterior (front) and posterior (back).
- Transverse Plane: Divides body into superior (upper) and inferior (lower) parts.

Common Anatomical Terms

Superior vs. Inferior: Above vs. below.
Anterior vs. Posterior: Front vs. back.
Medial vs. Lateral: Closer to the midline vs. farther from the midline.
Proximal vs. Distal: Closer to the trunk vs. farther from the trunk.
