Study Notes
Anatomy and Physiology
- Anatomy studies bodily structures; the term originates from Greek meaning "to cut apart."
- Physiology focuses on bodily processes and functions.
- Gross anatomy examines large structures visible without magnification; microscopic anatomy requires a microscope.
- Microscopic anatomy includes cytology (study of cells) and histology (study of tissues).
Levels of Organization
- Chemical: Interaction and combination of atoms into molecules.
- Cell: Basic structural and functional units of living organisms.
- Tissue: Groups of similar cells and surrounding materials.
- Organ: Composed of two or more tissue types functioning together.
- Organ System: Groups of organs that work as a unit due to common functions.
- Organism: Complex of organ systems mutually dependent on each other.
Organ Systems
- Integumentary
- Skeletal
- Muscular
- Nervous
- Endocrine
- Cardiovascular
- Lymphatic
- Respiratory
- Digestive
- Urinary
- Reproductive
Anatomical Position
- Defined as standing upright with the face forward, arms at the sides, palms facing forward.
- Supine position: lying face upward.
- Prone position: lying face downward.
- Central body regions include head, neck, trunk (thorax, abdomen, pelvis).
Body Parts and Regions
- Upper limb segments: arm (shoulder to elbow), forearm (elbow to wrist), wrist, hand.
- Lower limb segments: thigh (hip to knee), leg (knee to ankle), ankle, foot.
Abdominal Quadrants and Regions
- Abdomen divided into four quadrants: right-upper, left-upper, right-lower, left-lower using horizontal and vertical lines intersecting at the navel.
- Abdomen can also be divided into nine regions using four imaginary lines forming a tic-tac-toe grid:
- Epigastric
- Right and Left Hypochondriac
- Umbilical
- Right and Left Lumbar
- Hypogastric
- Right and Left Iliac
Anatomical Planes
- Transverse/Horizontal Plane: Divides the body into superior and inferior parts.
- Frontal/Coronal Plane: Divides the body into anterior and posterior parts.
- Sagittal Plane: Separates the body into right and left parts.
- Median Plane: Specific sagittal plane along the midline; divides the body into equal halves.
- Parasagittal Plane: An uneven sagittal plane.
Sections of Organs
- Longitudinal: Cut along the length of an organ.
- Transverse/Cross Section: Cut completely through an organ, similar to slicing a hot dog.
- Oblique: Diagonal cut across the long axis of an organ.
Trunk Cavities
- Thoracic Cavity: Enclosed by the rib cage, separated from the abdominal cavity by the diaphragm.
- Abdominal Cavity: Bounded by abdominal muscles, containing organs like stomach, intestines, liver, spleen, pancreas, and kidneys.
- Pelvic Cavity: Enclosed by pelvic bones, contains urinary bladder, part of large intestine, and reproductive organs.
Fun Questions (Terms and Relationships)
- Superior, inferior, anterior, posterior, lateral, medial, proximal, distal, superficial, deep, ipsilateral, contralateral are anatomical terms indicating locations and relationships between body parts.
