Study Notes
Anatomical Positions
- Prone: Lying face down
- Supine: Lying face up
- Lithotomy: Lying on the back with legs at a 90-degree angle
Anatomical Planes and Lines
- Vertical Plane (Median or Mid-Sagittal plane): Divides the body into equal right and left halves.
- Anterior and Posterior Lines: Imaginary lines running vertically along the front and back of the body.
- Sagittal Plane: Any plane parallel to the median plane.
- Coronal Plane: Divides the body into anterior and posterior sections.
- Transverse Plane: Divides the body into superior and inferior sections.
Anatomical Terms for Describing Planes and Relations
- Proximal: Closer to the origin of a structure.
- Distal: Further from the origin of a structure.
- Medial: Towards the midline of the body.
- Lateral: Away from the midline of the body.
- Superficial: Closer to the surface of the body.
- Deep: Further from the surface of the body.
- Superior: Above another structure.
- Inferior: Below another structure.
- Cephalic: In the head region.
- Caudal: In the tail region.
- Ventral: On the belly side.
- Dorsal: On the back side.
Anatomical Terms for Describing Movements
- Flexion: Decreasing the joint angle.
- Extension: Increasing the joint angle.
- Abduction: Movement away from the midline of the body.
- Adduction: Movement towards the midline of the body.
- Rotation: Turning around an axis.
- Circumduction: Circular movement.
- Pronation: Rotating the hand so the palm faces down.
- Supination: Rotating hand so the palm faces up.
- Dorsiflexion: Bending the foot upward.
- Plantarflexion: Bending the foot downward.
- Inversion: Turning the sole of the foot inwards.
- Eversion: Turning the sole of the foot outwards.
Anatomical Terms Describing Muscles
- Origin: The relatively fixed end of a muscle during movement.
- Insertion: The relatively mobile end of a muscle during movement.
- Belly: The fleshy, contractile part of the muscle.
- Tendon: The fibrous, non-contractile part of a muscle that attaches it to bone.
- Aponeurosis: A flattened tendon arising from the connective tissues around the muscle.
Body Tissues
-
Epithelial Tissues: Line or cover structures. Can be:
- Simple: Single layer.
- Stratified: Multiple layers.
-
Connective Tissues: Provide support, protection, and insulation
- Smooth Connective Tissue: Found in internal organs, blood vessels, and the digestive system.
-
Cartilagenous Connective Tissue: Provides flexibility and support:
- White Fibrocartilage: Found in intervertebral discs and menisci.
- Yellow Fibrocartilage: Found in the ear and epiglottis.
-
Bony Connective Tissue: Provides structural support and protection:
- Compact Bone: Dense, hard bone found in the shafts of long bones.
- Spongy Bone: Porous bone found in the ends of long bones.
Body Fascia
- Fascia: Band or sheet of connective tissue, primarily collagen, that supports and separates muscles and other tissues.
-
Superficial Fascia: The layer of loose connective tissue beneath the skin.
- Contains fat and water.
- Absent in the eyelid, ear, scrotum, penis, and clitoris.
-
Deep Fascia: Dense fibrous connective tissue surrounding individual muscles and dividing them into compartments.
- Rich in elastin fibers.
- Contains sensory receptors.
-
Visceral Fascia (Subserous Fascia): Connective tissue membranes that suspend and wrap organs within their cavities.
- Parietal Layer: Outermost layer.
- Visceral Layer: Innermost layer.
