Course Overview

This course provides a comprehensive introduction to regional anatomy and gross neuroanatomy, focusing on the structural and functional organization of the human body. Emphasis is placed on clinical correlations, developmental aspects, and the integration of anatomical knowledge with medical practice.

General Anatomy

Introduction and Generalities

• Anatomical Regions and Position: Understanding standard anatomical terminology is essential for describing locations and relationships of body parts.

• Anatomical Planes and Axes: The body is divided using planes (sagittal, coronal, transverse) and axes for precise localization.

• Movements: Terms describe movements of the vertebral column and limbs (e.g., flexion, extension, abduction, adduction).

• Diagnostic Imaging: Introduction to imaging techniques such as X-ray, CT, and MRI for anatomical visualization.

The Musculoskeletal System: Bones, Joints, and Skeletal Muscles

• Bone Structure and Classification: Bones are classified by shape (long, short, flat, irregular, sesamoid) and structure (compact and spongy).

• Joints: Classified by structure (fibrous, cartilaginous, synovial) and function (immovable, slightly movable, freely movable).

• Muscles: Skeletal muscles are organized into groups based on function and location; each muscle has specific attachments and innervation.

• Histology Integration: Bones, joints, and muscles are organs composed of multiple tissue types, each with distinct vascularization and innervation.

• Biomechanics: Principles of movement, support, and the mechanical properties of tissues are fundamental to understanding locomotion.

The Vascular Layout

• Body Vascularization: The circulatory system includes systemic and pulmonary circuits, with arteries, veins, and lymphatics.

• Deep/Superficial Vessels: Arterial and venous supply is organized into deep and superficial networks.

• Lymphatic Drainage: Lymphatic vessels return interstitial fluid to the bloodstream and are essential for immune function.

The Integumentary System

• Skin and Appendages: The skin is the largest organ, with regional features and appendages (hair, nails, glands) that serve protective and regulatory functions.

• Functional Anatomy: The skin provides a barrier, regulates temperature, and enables sensory perception.

The Skull

• Architecture: The skull is divided into the neurocranium (protects the brain) and splanchnocranium (facial skeleton).

• Development: Bones of the skull have distinct embryological origins and undergo ossification and age-related changes.

• Joints and Foramina: The skull contains numerous joints (sutures) and foramina for nerve and vessel passage.

• Surface Anatomy: Palpable landmarks are important for clinical examination and procedures.
