    Study Notes

    Anatomical Landmarks of Lower Limb

    • Inguen: Groin area
    • Pubis: Region surrounding the pubic bone
    • Femur: Thigh bone
    • Patella: Kneecap
    • Crus: Leg region
    • Tarsus: Ankle region
    • Pes: Foot
    • Planta: Sole of the foot
    • Hallux: Big toe
    • Digits: Toes
    • Gluteus: Buttock area
    • Popliteus: Back of the knee
    • Sura: Calf region
    • Calcaneus: Heel of the foot

    Anatomical Directions

    • Right: Refers to the right side of the subject
    • Left: Refers to the left side of the subject
    • Lateral: Away from the midline of the body
    • Medial: Toward the midline of the body
    • Proximal: Closer to the point of attachment
    • Distal: Further from the point of attachment
    • Superior: Above or toward the head
    • Inferior: Below or toward the feet
    • Superficial: Close to the body’s surface
    • Deep: Further away from the body’s surface
    • Cranial (Cephalic): Toward the head
    • Caudal: Toward the tail
    • Posterior (Dorsal): At the back
    • Anterior (Ventral): At the front
    • Supine: Lying on the back
    • Prone: Lying on the stomach

    Planes and Sections of the Body

    • Frontal Plane (Coronal Plane): Divides the body into anterior (front) and posterior (back) sections
    • Sagittal Plane: Divides the body into right and left parts
      • Midsagittal Section: Equal right and left halves
      • Parasagittal Section: Unequal right and left portions
    • Transverse Plane (Horizontal/Cross-Sectional Plane): Divides the body into superior (top) and inferior (bottom) parts

    Cell Types and Structure

    • Sex Cells (Germ/Reproductive Cells): Contain 23 chromosomes (e.g., sperm in males and oocytes in females)
    • Somatic Cells: Non-reproductive cells containing 46 chromosomes

    Human Cell and Organelle Sizes

    • Human Cells: Diameter ranges from 7 µm to 150 µm; average size is 10-15 µm, not visible to the naked eye
    • Organelles: Size varies from 20 nm to 10 µm, also not visible without a microscope

    Microscope Components

    • Composed of 26 bones:
      • 24 Vertebrae (7 cervical, 12 thoracic, 5 lumbar)
      • 1 Sacrum
      • 1 Coccyx

    Functions of the Vertebral Column

    • Protects the spinal cord and supports the skull
    • Transfers weight to lower limbs and aids in maintaining upright posture

    Major Types of Muscle Tissue

    • Skeletal Muscle: Voluntary and striated, attached to bones
    • Cardiac Muscle: Involuntary and striated, found in the heart
    • Smooth Muscle: Involuntary and non-striated, found in walls of organs and vessels

    Thoracic Cage

    • Composed of 25 bones: 1 sternum and 24 ribs
    • Protects vital thoracic cavity organs (e.g., heart, lungs)
    • Ribs classified as:
      • Vertebrosternal Ribs (1-7): Attach directly to the sternum
      • Vertebrochondral Ribs (8-10): Connect indirectly
      • Vertebral Ribs (11-12): No anterior attachment

    Integumentary System Components

    • Comprises Cutaneous Membrane (Epidermis and Dermis) and Accessory Structures (Hair Follicles, Exocrine Glands, Nails)

    Bone Markings

    • Spine: Sharp, slender projection
    • Fossa: Shallow indentation
    • Head: Expanded projection at the end of long bones

    Supporting Connective Tissue Types

    • Cartilage: Provides support and flexibility
    • Bone (Osseous Tissue): Solid, crystalline matrix composed of collagen fibers and calcium salts

    Specialized Bone Cells

    • Osteoprogenitor Cells: Stem cells that develop into bone cells
    • Osteocytes: Mature bone cells, important for bone maintenance
