Study Notes
Anatomy and Physiology
- Anatomy is the study of body structure and the relationships between its parts.
- Physiology is the study of how the body's systems work and how they maintain health.
- Pathophysiology is the study of abnormalities in the body and how they can cause illness.
- Pharmacology is the study of how drugs work in the body and how they can be used to treat illness.
Divisions of Anatomy
-
Gross Anatomy: The study of large structures that are visible to the naked eye.
- Regional anatomy: The study of structures in a specific region of the body.
- Systemic anatomy: The study of the structure of organ systems.
- Surface anatomy: The study of the structures that can be seen or felt on the surface of the body.
-
Microscopic Anatomy: The study of small structures that are not visible to the naked eye and require a microscope.
- Cytology: The study of cells.
- Histology: The study of tissues.
-
Developmental Anatomy: The study of the structural changes that occur in the body over time.
- Embryology: The study of the developmental changes that occur before birth.
Levels of Organization
- Chemical Level: The simplest level of organization, encompassing atoms and molecules.
- Molecular Level: Molecules combine to form more complex structures.
- Cellular Level: Cells are composed of molecules, representing the basic unit of life.
- Tissue Level: Similar cells group together to form tissues, with specialized functions.
- Organ Level: Different tissues work together to form organs, which perform specific tasks.
- System Level: Organs cooperate to form organ systems that carry out major bodily functions.
- Organism Level: The highest level of organization, consisting of all the organ systems working together to maintain life.
Anatomical Terminology
- Anatomical Position: A standard reference point for describing the body:
- Standing erect with feet together.
- Palms facing forward, thumbs pointing away from the body.
- Regions of the Body:
- Axial region: Head, neck, and trunk.
- Appendicular region: Limbs.
- Anatomical Planes: Imaginary flat surfaces used to divide the body:
- Sagittal Plane: Divides the body into left and right parts.
- Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back) parts.
- Transverse Plane: Divides the body into superior (top) and inferior (bottom) parts.
- Directional Terms: Describe the location of one structure relative to another:
- Superior (cranial, cephalic): Towards the head end.
- Inferior (caudal): Towards the tail end.
- Anterior (ventral): Towards the front.
- Posterior (dorsal): Towards the back.
- Medial: Towards the midline.
- Lateral: Away from the midline.
- Intermediate: Between two structures.
- Proximal: Closer to the origin of a body part.
- Distal: Farther from the origin of a body part.
- Superficial: Towards the body surface.
- Deep: Away from the body surface.
- Ipsilateral: On the same side of the body.
- Contralateral: On opposite sides of the body.
- Parietal: Relating to the outer wall of a body cavity.
- Visceral: Relating to the covering of an organ within a body cavity.
Body Cavities
-
Main Body Cavities:
- Cranial Cavity: Contains the brain.
- Vertebral Cavity: Contains the spinal cord.
- Thoracic Cavity:
- Pleural Cavities: Contain the lungs.
- Mediastinum: Space between the lungs, containing the heart, trachea, esophagus, and major blood vessels).
- Pericardial Cavity: Contains the heart.
- Abdominopelvic Cavity:
- Abdominal Cavity: Contains the stomach, intestines, liver, spleen, pancreas, and kidneys.
- Pelvic Cavity: Contains the bladder, reproductive organs, and rectum.
-
Small Body Cavities:
- Oral Cavity: Mouth.
- Nasal Cavity: Within the nose.
- Orbital Cavities: Hold the eyes.
- Middle Ear Cavities: Within the temporal bones, contain the ear ossicles.
- Synovial Cavities: Joint cavities, enclosed within fibrous capsules.
Abdominopelvic Regions and Quadrants
-
Abdominopelvic Regions: Nine regions used to describe the location of organs:
- Right hypochondriac: Right liver lobe.
- Right lumbar: Gallbladder and ascending colon.
- Right iliac: Cecum and appendix.
- Epigastric: Left liver lobe and stomach.
- Umbilical: Small intestines and transverse colon.
- Hypogastric: Urinary bladder.
- Left hypochondriac: Stomach.
- Left lumbar: Descending colon.
- Left iliac: Initial portion of the sigmoid colon.
-
Abdominopelvic Quadrants: Four quadrants defined by a median sagittal plane and a transverse plane intersecting at the umbilicus:
- Right Upper Quadrant (RUQ)
- Right Lower Quadrant (RLQ)
- Left Upper Quadrant (LUQ)
- Left Lower Quadrant (LLQ)
The Vertebral Column
- Flexible bony column extending from the base of the skull to the small of the back.
- Encloses the spinal cord.
- Articulates with the skull, ribs, and pelvic girdle.
- Provides attachment for back muscles.
- Vertebrae are connected by intervertebral discs and ligaments.
