Study Notes
Introduction of Anatomy
- Anatomy is the science of the structure and function of the body.
Objectives of Lecture
- Define Anatomy
- Define the anatomical position
- Describe important planes and sections
The Anatomical Position
- The standard reference position of the body used to describe the location of structures.
- Hands by the side
- Feet together
- Face looking forward
- Mouth closed
- Facial expression neutral
- Palms face forward with fingers straight
- Toes point forward
- Note: Palm & Sole (راحة اليد, راحة القدم)
Anatomical Planes
- A hypothetical plane used to transect the body in order to describe the location of the structure.
- Coronal plane: divides the body into anterior and posterior parts.
- Sagittal plane: divides the body into right and left parts
- Median plane: divides the body into equal right and left halves
- Transverse, horizontal, or axial plane; divides the body into superior and inferior parts.
Anatomical Sections
- Longitudinal section: runs length wise or parallel to the axis of the body or any of its parts.
- Transverse section (cross section): are slices of the body or parts.
- Oblique sections: are slices of the body or parts that are not cut along the listed anatomical planes.
Terms of Relationship
- Anterior & posterior: describe the position of structures relative to the 'front' and 'back' of the body
- Anterior: nearer to the front
- Posterior: nearer to the back
- In the trunk (ventral-dorsal)
- In the palm (palmar-dorsal)
- Superior & inferior: describe structures in reference to the vertical axis of the body
- Superior: nearer to the vertex
- Inferior: nearer to the sole
- Medial & lateral: describe the position of structures relative to the median plane
- Medial: nearer to the median plane
- Lateral: away from the median plane
- Proximal & distal: used with reference to the origin or attachment of a structure, particularly in the limbs
- Proximal: nearer to origin
- Distal: away from origin
- Superficial & deep: describe the relative positions of structures with respect to the surface of the body
- Superficial: nearer to surface
- Deep: away from surface
- External & internal: describe the position in relation to the center
- External: away from center
- Internal: nearer to center
Hand
- Parts of the hand include: palm, back, nails, fingers, knuckles, and wrist.
Part of the Hand
- Detailed parts of the hand including index finger, middle finger, ring finger, little finger, thumb.
Note of the Prefix
- uni=1
- bi=2
- tri=3
- tetra=4
- penta=5
- hexa=6
Terms of Laterality
- Bilateral: paired structure present on both sides (e.g., kidneys)
- Unilateral: unpaired structure present on one side (e.g., spleen)
- Ipsilateral: relating things to the same side of the body
- Contralateral: relating things to the different side of the body
Terms Related to Movement
- Joint: site where two or more bones come together
- Types of joints:
- No movement (e.g., sutures of the skull)
- Slight movement (e.g., superior tibiofibular joint)
- Freely movable (e.g., shoulder joint)
Movements
- Flexion: a movement that takes place in a sagittal plane
- Extension: straightening the joint, usually in a posterior direction
- Abduction: movement of a limb away from the midline of the body in the coronal plane
- Adduction: movement of a limb toward the body in the coronal plane
- Medial rotation: movement that results in the anterior surface of the part facing medially
- Lateral rotation: movement that results in the anterior surface of the part facing laterally
- Supination: palm faces up
- Pronation: palm faces down
- Inversion: movement of the sole of the foot inward (medially)
- Eversion: movement of the sole of the foot outward (laterally)
