🦴 INTRODUCTION TO ANATOMY
🔹 Definition
Anatomy is the branch of medicine that deals with the structure of the human body. It is broadly divided into:
- Gross Anatomy
- Histology (Microscopic)
- Embryology
- Surface Anatomy
- Radiological Anatomy
- Clinical Anatomy
🔹 Anatomical Position
- Standing erect
- Arms by the side
- Palms facing forward
- Feet slightly apart
- Eyes looking straight ahead
🧍♂️ BRANCHES OF ANATOMY
| Branch | Description |
|---|---|
| Gross Anatomy | Study of structures visible to naked eye |
| Microscopic Anatomy (Histology) | Study under microscope |
| Embryology | Development of embryo & fetus |
| Surface Anatomy | External landmarks |
| Radiological Anatomy | Study using imaging (X-ray, CT, MRI) |
| Clinical Anatomy | Applied aspects in clinical practice |
🗺️ PLANES AND TERMS
| Term | Meaning |
|---|---|
| Sagittal Plane | Divides body into left and right |
| Coronal Plane | Divides body into front (anterior) & back (posterior) |
| Transverse Plane | Divides into upper (superior) & lower (inferior) parts |
Directional Terms:
- Anterior ↔ Posterior
- Superior ↔ Inferior
- Medial ↔ Lateral
- Proximal ↔ Distal
- Superficial ↔ Deep
🧬 TISSUES OF BODY
1. Epithelial Tissue
- Covers body surfaces, lines cavities
- Types: Squamous, Cuboidal, Columnar, Transitional
2. Connective Tissue
- Supports and binds tissues
- Types: Loose (areolar), Dense, Cartilage, Bone, Blood
3. Muscle Tissue
- Responsible for movement
- Types: Skeletal, Cardiac, Smooth
4. Nervous Tissue
- Transmits electrical signals
- Found in brain, spinal cord, nerves
🔧 STRUCTURE OF BONES
| Type | Example |
|---|---|
| Long bones | Femur, Humerus |
| Short bones | Carpal bones |
| Flat bones | Skull, Ribs |
| Irregular bones | Vertebrae |
| Sesamoid bones | Patella |
Bone Parts:
- Diaphysis, Epiphysis, Metaphysis
- Periosteum, Endosteum
- Medullary cavity
💉 BLOOD SUPPLY & INNERVATION
- End arteries: Arteries with no anastomoses
- Veins: Superficial and deep
- Lymphatics: Drain interstitial fluid
- Nerves: Sensory and motor supply
⚙️ JOINTS
| Type | Subtypes | Examples |
|---|---|---|
| Fibrous | Sutures | Skull |
| Cartilaginous | Symphysis | Pubic symphysis |
| Synovial | Hinge, Ball & Socket | Elbow, Shoulder |
❤️🩹 CLINICAL ANATOMY TIPS
- Fractures → Disruption in bone continuity
- Dislocations → Bone displacement from joint
- Hernia → Organ protrusion
- Bursitis → Inflammation of bursa
- Lymphadenopathy → Enlarged lymph nodes
❓ Frequently Asked Questions (Theory)
Q1. Define Anatomy. What are its branches?

Q3. Name the types of joints with examples.
→ Fibrous – sutures in skull
Cartilaginous – intervertebral discs
Synovial – shoulder (ball and socket)
Q4. Define anatomical position.
→ Standing upright, arms at sides, palms forward, feet apart, eyes forward.

The main branches of Anatomy include Gross Anatomy (study of structures visible to the naked eye), Microscopic Anatomy (Histology), Embryology (development of embryo & fetus), Surface Anatomy (external landmarks), Radiological Anatomy (study using imaging like X-rays, CT, MRI), and Clinical Anatomy (applied aspects in medical practice).
What is the Anatomical Position?
expand_more
The Anatomical Position is a standardized reference posture used in anatomy and medicine. It describes a person standing erect, with arms by their sides, palms facing forward, feet slightly apart, and eyes looking straight ahead. This position ensures consistent description of body parts and locations.
