Study Notes
Introduction to Human Anatomy
- Human anatomy is the study of the form and structure of the human body and the relationship of its constituent parts to each other.
- Anatomy is the process of cutting up the body.
- Anatomy subdisciplines are gross or macroscopic, comparative, developmental, regional, surface, clinical and systemic anatomy and embryology.
- Microscopic anatomy comprises of cytology and histology.
Learning Outcomes
- Define anatomical planes, directional terms and movements of the body.
- Describe the structural organization of the body.
- Describe the orientation of the body in anatomical position.
- Describe the basic tissues and membranes.
- Relate structures to their respective body regions, cavities and membranes.
Anatomical Position
- Stand upright, with feet together and directed forward, and eyes looking forward.
- Upper limbs are by the side with palms facing forwards and thumbs pointing away from the body.
Planes & Sections
- Mid-sagittal/Median Plane: Divides the body into equal right and left halves.
- Sagittal/Parasagittal Plane: Divides the body into unequal right and left parts. Any vertical plane parallel to the median plane.
- Frontal/Coronal Plane: Divides the body into anterior (front) and posterior (back) parts. A vertical plane that is perpendicular to the median plane.
- Cross-sectional/Transverse Plane: Divides the body into superior (top) and inferior (bottom) parts. A horizontal plane, perpendicular to both the median and coronal planes.
- Oblique Plane: Passes through the body at an angle.
Directions
- Anterior/Ventral: Towards the front of the body.
- Posterior/Dorsal: Towards the back of the body.
- Superior/Cranial: Towards the head.
- Inferior/Caudal: Away from the head, towards the feet.
- Medial: Towards the midline of the body.
- Lateral: Away from the midline of the body.
- Proximal: Closer to the point of attachment of an appendage to the trunk.
- Distal: Farther from the point of attachment of an appendage to the trunk.
- Superficial: Closer to the body surface.
- Deep: Further away from the body surface.
Angular Movements
- Flexion: Decreases the angle between two bones.
- Extension: Increases the angle between two bones.
- Hyperextension: Extension beyond the normal anatomical position.
- Lateral Flexion: Bending the trunk sideways.
Angular Movements...
- Abduction: Movement of a limb away from the midline of the body.
- Adduction: Movement of a limb toward the midline of the body.
- Circumduction: Circular movement of a limb.
Rotational Movements
- Medial Rotation: Rotation of a limb inwards towards the midline of the body.
- Lateral Rotation: Rotation of a limb outwards away from the midline of the body.
- Pronation: The rotation of the forearm so the palm faces posteriorly.
- Supination: The rotation of the forearm so the palm faces anteriorly.
Special Movements
- Depression: Movement of a body part inferiorly.
- Elevation: Movement of a body part superiorly.
- Protraction: Movement of a body part anteriorly.
- Retraction: Movement of a body part posteriorly.
- Inversion: Turning the sole of the foot inward.
- Eversion: Turning the sole of the foot outward.
- Dorsiflexion: Bending the foot (and toes) upward.
- Plantar Flexion: Bending the foot (and toes) downward.
Body Regions and Cavities
- Axial Regions: Head, Neck, Trunk, Upper Limb, Lower Limb
- Body Cavities: Dorsal (cranial, vertebral) and Ventral (thoracic, abdominal, pelvic)
Body Cavities
- Dorsal Body Cavity: Cranial cavity and Vertebral cavity.
- Ventral Body Cavity: Thoracic cavity, Pleural cavities, Pericardial cavity, Abdominopelvic cavity, Abdominal cavity, Pelvic cavity
Body Regions
- Abdominopelvic regions / quandrants
Body Membranes
- Epithelial Membranes: Mucous, Serous, Cutaneous.
- Synovial Membranes: Lines the fibrous capsules surrounding the joints.
- Connective tissue (lamina propria), epithelium,
- Adapted for absorption and secretion depending upon the location..
Levels of Human Body Organization
- Atom
- Molecule
- Macromolecule
- Organelle
- Cell
- Tissue
- Organ
- Organ System
- Organism
Systems of Human Body
- Musculoskeletal, Circulatory, Nervous, Lymphatic, Respiratory, Endocrine, Digestive, Excretory, Reproductive, Integumentary
Cellular Level
- Cytology: Study of individual cells.
- Cells have varying shapes, sizes and functions.
- Components of a cell: plasma membrane, cytoplasm (cytosol, organelles), nucleus.
- Cell junctions: tight junctions, adherens junctions, desmosomes, hemidesmosomes, gap junctions.
Tissue Level
- Basic tissues: Epithelial, Connective, Muscle, Nervous.
- Epithelial tissues: Surface, Glandular
- Consist of cells in continuous sheets, highly cellular, avascular (lack blood vessels), and regenerate easily
- Loose and dense connective tissues, specialised cartilage, bone, blood and lymph compose this tissue.
