🦴 INTRODUCTION TO ANATOMY

πŸ”Ή 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

πŸ”Ή Anatomical Position

  • Standing erect
  • Arms by the side
  • Palms facing forward
  • Feet slightly apart
  • Eyes looking straight ahead

πŸ§β€β™‚οΈ 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

πŸ—ΊοΈ 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

πŸ”§ 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

πŸ’‰ BLOOD SUPPLY & INNERVATION

  • End arteries: Arteries with no anastomoses
  • Veins: Superficial and deep
  • Lymphatics: Drain interstitial fluid
  • Nerves: Sensory and motor supply

βš™οΈ JOINTS

Type Subtypes Examples
Fibrous Sutures Skull
Cartilaginous Symphysis Pubic symphysis
Synovial Hinge, Ball & Socket Elbow, Shoulder

β€οΈβ€πŸ©Ή CLINICAL ANATOMY TIPS

  • Fractures β†’ Disruption in bone continuity
  • Dislocations β†’ Bone displacement from joint
  • Hernia β†’ Organ protrusion
  • Bursitis β†’ Inflammation of bursa
  • Lymphadenopathy β†’ Enlarged lymph nodes

❓ Frequently Asked Questions (Theory)

Q1. Define Anatomy. What are its branches?
β†’ Anatomy is the study of structure of human body. Its branches include gross anatomy, histology, embryology, clinical anatomy, radiological anatomy, etc.

Q2. Classify bones with examples.
β†’ Long bones (humerus), short bones (carpals), flat bones (skull), irregular bones (vertebra), sesamoid bones (patella).

Q3. Name the types of joints with examples.
β†’ Fibrous – sutures in skull
Cartilaginous – intervertebral discs
Synovial – shoulder (ball and socket)

Q4. Define anatomical position.
β†’ Standing upright, arms at sides, palms forward, feet apart, eyes forward.
