Skeleton worksheet - Free Printable

The task is to label the parts of the skeletal system in the provided image using the given bone names. Below is the solution with explanations for each part:

Step-by-Step Solution:

1. Skull:
- The skull is the bony structure that protects the brain and supports the face.
- Location: Top of the skeleton.
- Label: Connect the topmost blue arrow to "SKULL."

2. Ribs:
- The ribs are a series of bones that form a protective cage around the chest, protecting the heart and lungs.
- Location: Curved bones extending from the spine to the front of the chest.
- Label: Connect the arrows near the chest area to "RIBS."

3. Spine:
- The spine (or vertebral column) is a series of bones stacked on top of each other, providing support and flexibility to the body.
- Location: The long vertical column of bones running down the back.
- Label: Connect the central vertical arrow to "SPINE."

4. Pelvis:
- The pelvis is a bony structure that connects the spine to the legs and supports the lower organs.
- Location: The hip area, below the spine and above the thighs.
- Label: Connect the arrow near the hip area to "PELVIS."

5. Upper Arm Bone:
- The upper arm bone is called the humerus. It connects the shoulder to the elbow.
- Location: The long bone in the upper arm.
- Label: Connect the arrow near the upper arm to "UPPER ARM BONE."

6. Lower Arm Bone:
- The lower arm consists of two bones: the radius and ulna. For simplicity, we can refer to this as the "lower arm bone."
- Location: The two bones in the forearm, between the elbow and wrist.
- Label: Connect the arrow near the forearm to "LOWER ARM BONE."

7. Hand Bones:
- The hand bones include the carpals (wrist bones), metacarpals (palm bones), and phalanges (finger bones).
- Location: The bones in the hand.
- Label: Connect the arrow near the hand to "HAND BONES."

8. Thigh Bone:
- The thigh bone is called the femur. It is the longest bone in the human body and connects the hip to the knee.
- Location: The long bone in the thigh.
- Label: Connect the arrow near the thigh to "THIGH BONE."

9. Lower Leg Bone:
- The lower leg consists of two bones: the tibia (shinbone) and fibula. For simplicity, we can refer to this as the "lower leg bone."
- Location: The two bones in the lower leg, between the knee and ankle.
- Label: Connect the arrow near the lower leg to "LOWER LEG BONE."

10. Foot Bones:
- The foot bones include the tarsals (ankle bones), metatarsals (bones of the midfoot), and phalanges (toe bones).
- Location: The bones in the foot.
- Label: Connect the arrow near the foot to "FOOT BONES."

Final Answer:

Here is the labeled skeletal system based on the provided labels:

- Top of the head: SKULL
- Chest area: RIBS
- Back column: SPINE
- Hip area: PELVIS
- Upper arm: UPPER ARM BONE
- Forearm: LOWER ARM BONE
- Hand: HAND BONES
- Thigh: THIGH BONE
- Lower leg: LOWER LEG BONE
- Foot: FOOT BONES

Explanation:

Each bone or group of bones has a specific function and location in the body. By understanding their roles and positions, you can accurately label them. This exercise helps reinforce knowledge of the human skeletal system.

Final Answer Box:
\boxed{
\text{SKULL, RIBS, SPINE, PELVIS, UPPER ARM BONE, LOWER ARM BONE, HAND BONES, THIGH BONE, LOWER LEG BONE, FOOT BONES}
