1. What is the skeletal composition?Each hand comprises 27 bones: 8 carpals, 5 metacarpals, and 14 phalanges
2. What is the sensory receptors?High concentration of mechanoreceptors (Meissner's, Pacinian, Merkel, Ruffini) provides acute tactile sensitivity
3. What makes our hands so strong and flexible?Our hands have 27 bones and 29 muscles that work together to give us powerful grips and delicate movements. The bones are connected by joints that let us bend and stretch in many ways.
4. How does the thumb help us pick up things?The thumb can move opposite to the other fingers because of a special saddle joint. This lets us hold objects tightly and with great precision.

Carpals: The eight small bones forming the wrist.
Metacarpals: The five bones in the palm connecting the wrist to the fingers.
Phalanges: The bones of the fingers and thumb, with three in each finger and two in the thumb.
Mechanoreceptors: Sensory nerve endings that respond to mechanical stimuli like pressure and vibration.
