Study Notes
Anatomy
- Anatomy is the study of body structures that are visible grossly (without magnification) and microscopically (with magnification).
- Gross anatomy is the study of structures visible without a microscope.
- Histology is the microscopic study of cells and tissues.
- Anatomy is a basis for medicine. It helps doctors understand a patient's disease during physical exams and with advanced imaging techniques.
- Anatomy is crucial for other related professions like dentistry, chiropractic, and physical therapy.
- Observation and visualization are key techniques for learning anatomy.
- Anatomy involves more than memorization of names. It's about understanding the context of structures.
- Two approaches to studying anatomy are regional (studying a region of the body at once) or systemic (studying a specific system, then examining the body regionally). Regional may be better with dissection.
Anatomical Position
- The anatomical position is a standard reference position for the body.
- The subject stands erect, feet together, hands at their sides with palms forward, facing forward, and eyes focused on something distant.
Anatomical Planes
- Three main planes slice through the body in the
anatomical position
- Sagittal (divides body into right/left parts),
- Coronal (divides body into anterior/posterior parts),
- Transverse (divides body into superior/inferior parts).
Important Anatomical Terms
- Anterior (ventral): Front of the body.
- Posterior (dorsal): Back of the body.
- Medial: Towards the midline of the body.
- Lateral: Away from the midline of the body.
- Superior: Above or higher.
- Inferior: Below or lower.
- Proximal: Closer to the point of origin of a limb.
- Distal: Further from the point of origin of a limb.
- Cranial (cephalic): Towards the head.
- Caudal: Towards the tail.
- Rostral: Towards the nose (used primarily for the head).
- Superficial: Closer to surface.
- Deep: Further from the surface.
