Overview of Today's Lecture

• Topic: General Anatomy Part 1
• Focus: Understanding the concept of anatomy, its basic terms, and the division of anatomy into different parts

Key Concepts Discussed

Definition of Anatomy

• Anatomy: Derived from Latin terms where 'Anna' means 'to see' and 'Tomy' means 'to cut'. Thus, anatomy means 'cut and observe'.
• Objective: Study of the human body structure through dissection of dead bodies (referred to as cadavers)

Importance of Anatomy

• Foundation for understanding the function and diseases in medical practice
• Essential for studying Orthopedics, Surgery, Radiology, etc.

Division of Anatomy

1. Regional Anatomy

   • Study of the body divided into regions (e.g., head, neck, thorax, abdomen, etc.)
   • Each part is studied independently

2. Systemic Anatomy

   • Study of the body based on systems (e.g., cardiovascular, respiratory, nervous systems, etc.)
   • Entire system studied at once

Regions of the Body

• Head and Neck: Includes the face and skull
• Thorax: Contains heart and lungs
• Abdomen and Pelvis: Separated by the diaphragm
• Upper Limb: Shoulder, arm, forearm, and hand
• Lower Limb: Hip, thigh, leg, and foot
• Back and Gluteal Region: Back and buttocks

Anatomical Position

• Standard Anatomical Position: Reference for anatomical nomenclature
  • Person stands upright, facing forward
  • Arms abducted with palms forward
  • Feet parallel

Transverse Section of the Limb

• Layers from outside to inside: Skin, Superficial fascia, Deep fascia, Skeletal muscles, Bone

• Superficial Fascia:

  • Lies just under the skin
  • Composed of loose areolar tissue and adipose tissue
  • Functions: insulation, protection, allows skin movement

• Deep Fascia:

  • Non-elastic, tough fibrous tissue
  • Envelopes muscles and neurovascular bundles
  • Functions: protection, support circulation, forms sheaths

Important Terms and Definitions

• Intermuscular Space: Space between muscles containing veins, arteries, and nerves (neurovascular bundle)

  • Divided into anterior and posterior compartments by the intermuscular septum

• Hilton’s Law: Nerve supplying a muscle innervates the skin and joint associated with the muscle

Practice Questions

• Clinical scenario involving anatomical position: Emphasized understanding the standard anatomical position

Homework

• Diagram labeling for anatomical regions
