    Study Notes

    Human Body Overview

    • Comprised of two main regions: axial (torso) and appendicular (limbs).
    • Axial region includes head, neck, thorax, abdomen, pelvis, and perineum.
    • Appendicular region includes upper and lower limbs.

    Axial Region

    • Head: Top part of the body with neurocranium (skull) and viscerocranium (face).
    • Neck: Connects head to thorax, starts from the first cervical vertebra.
    • Thorax: Extends from the first thoracic vertebra down to the sternum, contains lungs and heart within pleural cavities and mediastinum.

    Appendicular Region

    • Upper Limb: Includes shoulder, arm, forearm, elbow, wrist, and hand; important bone is the humerus.
    • Lower Limb: Comprises thigh, leg, and foot.

    Skull and Facial Structure

    • Skull: Composed of cranial bones and facial bones, supports the brain.
    • Viscerocranium: Includes eye sockets, nasal cavity, zygoma, maxilla, and mandible.
    • Buccal Cavity: First part of the digestive system.

    Connective Tissue

    • Loose Connective Tissue (Areolar Tissue): Binds organs and structures, serves as packing material.
    • Periosteum: Membrane covering bones, contains blood vessels and cells for growth and repair.

    Muscles and Functional Systems

    • Upper Limb Muscles:
      • Rotator Cuff Muscles: Includes deltoid, supraspinatus, infraspinatus, teres minor, subscapularis.
      • Flexor Muscles: Biceps brachii, flexor carpi ulnaris, flexor digitorum superficialis, etc.
      • Extensor Muscles: Extensor carpi ulnaris, extensor digitorum.

    Lower Limb Structure

    • Thigh Muscles: Comprised of quadriceps (extension) and hamstring muscles (flexion).
    • Leg Structure: Contains tibia (shin bone) and fibula; divided into anterior, posterior, and lateral compartments.

    Body Cavities

    • Dorsal Body Cavity: Houses brain and spinal cord.
    • Ventral Body Cavity: Contains organs within the thoracic and abdominal regions.

    Abdomen-Pelvic Region

    • No membrane separating abdominal and pelvic cavities, crucial for organ protection.
    • Divided into nine regions and four quadrants for clinical purposes.

    Foot Anatomy

    • Composed of 22 bones: 7 tarsals, 5 metatarsals, and 10 phalanges.
    • Important for stability and movement, with arches allowing for mobility.

    Additional Notes

    • Pes Planus: Flat foot condition characterized by flattened arches.
    • Connective Tissues: Facilitate support and organization of the body’s structures, include periosteum which is vital for bone health.
