Study Notes
Introduction to Anatomical Terms & Planes
- Anatomy is the science of human body structure.
- It forms the foundation of medicine.
- Medical terminology is introduced through anatomy.
- The word "anatomy" is derived from Greek words meaning "to cut up".
Subdivisions of Anatomy
- Gross (cadaveric) anatomy involves studying the structure of embalmed dead bodies. This can be done regionally (like upper/lower limbs) or systemically (like skeletal, muscular, nervous, and respiratory systems).
- Living anatomy involves observing and examining living human beings directly or via technology like radiography and endoscopy.
Histology/Microscopic Anatomy
- Histology is the microscopic study of tissues.
Embryology (Developmental Anatomy)
- Embryology examines prenatal developmental changes.
Neuroanatomy
- This is the study of the nervous system's structure and organization.
Topographic Anatomy (Surface Anatomy)
- This involves understanding the relationship between deep body parts and the skin surface.
Radiographic & Imaging Anatomy
- This uses techniques like plain/contrast radiography and CT scans.
Applied (Clinical) Anatomy
- This applies anatomical knowledge to medical and surgical practice.
Descriptive Terms: Position of the Body
- Anatomical position: A person standing upright, facing forward, arms at the sides, palms forward, feet together.
- Supine position: lying on the back, face upward.
- Prone position: lying on the stomach, face downward.
- Lithotomy position: lying on the back with legs raised and supported.
Body Planes and Sections
- Median (midsagittal) plane: divides the body into right and left halves.
- Sagittal plane: parallel to the median plane.
- Coronal plane: perpendicular to the sagittal plane, dividing the body into anterior (front) and posterior (back) parts.
- Transverse plane: perpendicular to both sagittal and coronal planes, dividing the body into superior (top) and inferior (bottom) parts.
Terms of Relationship
- Anterior (Ventral): toward the front of the body.
- Posterior (Dorsal): toward the back of the body.
- Superior (Cranial/Cephalic): toward the head.
- Inferior (Caudal): toward the feet.
- Medial: closer to the midline of the body.
- Lateral: farther from the midline of the body.
Terms of Comparison
- Proximal: Closer to the trunk or point of origin.
- Distal: Further from the trunk or point of origin.
- Superficial: Closer to the surface.
- Deep: Further from the surface.
- External: Outside.
- Internal: Inside.
- Central: Near the center.
- Peripheral: Away from the center.
- Ipsilateral: On the same side of the body.
- Contralateral: On the opposite side of the body.
Terms Describing Movements at Joints
- Flexion: Decreasing the angle between bones.
- Extension: Increasing the angle between bones.
- Abduction: Moving away from the midline.
- Adduction: Moving towards the midline.
- Rotation: Movement around a central axis.
- Medial Rotation: Turning the anterior surface of a limb towards the midline.
- Lateral Rotation: Turning the anterior surface of a limb away from the midline.
- Circumduction: Circular movement combining flexion, abduction, extension, and adduction.
- Protrusion: Moving a body part forward.
- Retraction: Moving a body part backward.
Terms Related to Muscles
- Origin: The fixed point of attachment of a muscle on a bone.
- Insertion: The movable point of attachment of a muscle on a bone.
- Belly: The fleshy part of a muscle.
- Tendon: The fibrous part of a muscle that connects the muscle to a bone or other structure.
- Aponeurosis: A broad, flat tendon.
Terms Related to Nerves
- Motor (efferent) nerves: transmit signals from the central nervous system to muscles.
- Sensory (afferent) nerves: transmit signals from sensory receptors to the central nervous system.
Terms Related to Blood Vessels
- Arteries: Carry oxygenated blood away from the heart (except pulmonary and umbilical arteries).
- Veins: Carry deoxygenated blood to the heart.
- Arterioles: Small branches of arteries within the tissue.
- Venules: Small vessels that collect blood from capillaries and merge into veins.
- Capillaries: Tiny blood vessels where exchange of oxygen, nutrients, and waste products occurs.
- Anastomosis: Connections between blood vessels. Blood vessels can also have a singular form of joining.
Terms Used for Describing Bone Features
- Elevations: Projections on bones (e.g., tubercle, tuberosity, condyle, epicondyle, malleolus).
- Depressions: Cavities on bones (e.g., fossa, groove, notch, fovea).
- Openings: Passages through bones (e.g., foramen, canal).
- Cavities: Spaces within bones (e.g., sinus).
Basic Tissues of the Body
- Cells are the functional and structural units of the body. (e.g. epithelial, muscle, nerve, connective, cartilage, bone)
Tissues: Defined
- Tissues: Groups of cells with similar structure and function. (e.g., epithelial, connective, muscular, neural and specialized connective tissues like bone, cartilage, and blood)
Organs: Defined
- Organs: Structures made up of different types of tissues working together to perform specific functions. (e.g., heart, kidney, lungs)
Organ Systems
- Organ systems: Groups of organs that work together to perform specific functions. (e.g., gastrointestinal, respiratory, cardiovascular and urinary)
Urinary System Components
- The urinary system is responsible for eliminating waste products from the body.
- Parts include the kidneys, ureters, bladder and urethra.
Digestive System Components
- Digesting food and absorbing nutrients.
- Includes the oral cavity, esophagus, stomach, small and large intestines, the liver, anus, and rectum.
