Study Notes
Definition of Anatomy
- Anatomy is the study of the structure and shape of the body and its parts and their relationships.
- The primary goal of anatomy is to assist medical students in understanding internal body structures for effective medical practice.
Methods of Studying Anatomy
- Dissection: Traditional method involving cutting the body to study organ shape and relations.
- Cadaver: Preserved body used for dissection studies.
Sub-Divisions of Anatomy
- Living Anatomy: Examines organ sites and shapes from the exterior of living individuals.
- Embryology: Focuses on the development of organs during intra-uterine life.
- Histology: Studies the structure and ultra structure of organs using microscopy.
- Endoscopy: Involves examining the interior of the body using endoscopes.
- Comparative Anatomy: Compares human anatomy with that of other vertebrates.
- Radiological Anatomy: Utilizes radiological films to study body anatomy.
Human Anatomy Classifications
- Regional Anatomy: Divided into specific regions such as head and neck, thorax, abdomen and pelvis, upper limb, and lower limb.
- Systemic Anatomy: Involves systems like integumentary, musculo-skeletal, nervous, cardiovascular, digestive, respiratory, urinary, reproductive, and endocrine.
Anatomical Planes
- Median Sagittal Plane: Divides the body into equal right and left halves.
- Para Sagittal Plane: Divides the body into unequal right and left parts, parallel to the median plane.
- Coronal Plane: Divides the body into anterior (front) and posterior (back) parts.
- Horizontal Plane (Transverse): Divides the body into upper and lower parts.
Anatomical Position
- Body in erect posture, facing forward, arms by sides, feet close together, palms and eyes directed forward.
Anatomical Terms of Position
- Median: At the midline.
- Medial: Near the midline.
- Lateral: Away from the midline.
- Superior (Cranial): Near the head.
- Inferior (Caudal): Near the feet.
- Proximal: Closer to the trunk (in limbs).
- Distal: Further from the trunk (in limbs).
- Anterior (Ventral): Near the front.
- Posterior (Dorsal): Near the back.
- Palmar: Anterior surface of the hand.
- Plantar: Sole of the foot.
- Superficial: Nearer to the body surface.
- Deep: Away from the body surface.
- Ipsilateral: Same side.
- Contralateral: Opposite side.
Body Positions
- Supine Position: Lying on the back.
- Prone Position: Lying face downward.
- Lithotomy Position: Used for examinations or operations in urology, gynecology, proctology, and childbirth.
Terms Related to Movement
- Extension: Increasing the angle between articulating bones.
- Flexion: Decreasing the angle between articulating bones.
- Adduction: Movement toward the median plane.
- Abduction: Movement away from the median plane.
- Medial Rotation: Movement toward the median plane along the vertical axis.
- Lateral Rotation: Movement away from the median plane along the vertical axis.
