Study Notes
Anatomy Definition
- Anatomy is the study of the structure, arrangement, and geography of the human body.
- It is the foundation of all medical sciences.
- Can be approached systematically (descriptive anatomy), macroscopically, or microscopically.
Human Body Organization
- The human body is organized in a hierarchical manner: cells form tissues, tissues form organs, organs form systems, and all systems together constitute the human body.
Anatomical Position
- The standardized reference position for describing the body:
- Body stands erect, feet together, face forward.
- Upper limbs are at the sides with palms facing forward.
Anatomical Terms
-
Anterior/Posterior (Ventral/Dorsal):
- Anterior: Front of the body.
- Posterior: Back of the body.
- Palmar: ventral surface of the hand.
- Planter: sole of the foot.
-
Proximal/Distal:
- Proximal: Closer to the origin of a structure (e.g., shoulder joint).
- Distal: Further away from the origin of a structure (e.g., fingertips).
-
External/Internal (Superficial/Deep):
- External/Superficial: Closer to the surface of the body.
- Internal/Deep: Closer to the center of the body.
-
Superior/Inferior (Cranial/Caudal):
- Superior/Cranial: Above another structure.
- Inferior/Caudal: Below another structure.
-
Median/Medial/Lateral:
- Median: Mid-sagittal plane.
- Medial: Towards the mid-sagittal plane.
- Lateral: Away from the mid-sagittal plane (towards the side of the body).
Anatomical Planes
- Midsagittal Plane: Divides the body into equal right and left halves.
- Sagittal Plane: Divides the body into unequal right and left parts.
- Coronal Plane: Divides the body into anterior and posterior parts.
- Transverse (Horizontal) Plane: Divides the body into upper and lower parts.
Gross Anatomy Divisions
-
Regions:
- Head and neck.
- Trunk (thorax, abdomen, pelvis).
- Limbs (upper and lower limbs).
-
Systems:
- Locomotor: Bones, muscles, joints.
- Nervous: Brain, spinal cord, nerves.
- Digestive: Gastrointestinal tract (GIT).
- Endocrine: Glands that secrete hormones.
- Genital: Reproductive organs.
- Lymphatic: Immune system.
