How many bones are in your hand?

Use a pencil to trace an outline of your hand on a piece of paper. Feel the bones in your fingers and the palm of your hand. At points where you can bend your fingers and hand, draw a circle. Each circle represents a joint where two bones meet. Draw lines to represent the bones in your hand.

How many bones did you find? How many joints?

There are 19 bones in a hand and 14 joints. A joint allows movement between two bones.

SECTION OUTLINESECTION OUTLINE

homeostasis

You can think of the body as having five levels of organization: cells, tissues, organs, organ systems, and the whole organism itself. The different systems of the human body work together to maintain homeostasis.

Organism (human)

Cells (cardiac muscle cells)

Tissue (cardiac muscle) Organ (heart) Organ system (circulatory

axial skeleton


Bones are living tissue. The skeleton is the body's framework and has two main divisions, the axial skeleton and the appendicular skeleton. Bones come together at joints.
