Can you define these anatomical terms: Dorsum, Dorsal surface, Palmar surface, Plantar surface, Infomedial, Superolateral, Superficial, Intermediate, Deep, External, Internal?

Let's explain these anatomical terms, عبمان.

1. Dorsum: This refers to the superior aspect (top surface) of any part that protrudes anteriorly from the body, like the top of the foot or the back of the hand.
2. Dorsal surface: Specifically, this is the surface of the hands and feet that corresponds to the dorsum. For the hand, it's the back of the hand; for the foot, it's the top of the foot.
3. Palmar surface: This is the surface of the hands and fingers that corresponds to the palm.
4. Plantar surface: This is the surface of the foot and toes that corresponds to the sole (the bottom surface).
5. Infomedial: This describes a position that is nearer to the feet (inferior) and nearer to the midline (medial) of the body.
6. Superolateral: This describes a position that is nearer to the head (superior) and further from the midline (lateral) of the body.
7. Superficial, Intermediate, and Deep: These terms describe the position of structures relative to the surface of the body.
   • Superficial: Closer to the surface.
   • Intermediate: Between a superficial and a deep structure.
   • Deep: Further from the surface.
8. External: Means further from the center of an organ or cavity.
9. Internal: Means inside or closer to the center of an organ or cavity.
10. Proximal & Distal: These are contrasting positions used when referring to a limb or a linear structure.
    • Proximal: Nearer to the attachment of a limb to the trunk or the central aspect of a linear structure.
    • Distal: Further from the attachment of a limb to the trunk or the central aspect of a linear structure.
11. Bilateral: Refers to paired structures that have both a right and a left member, like your arms or kidneys.
