There are two types of bone marrow, yellow and red, one of them is used when you are a child and the other is used when you're an adult. Which color do you use when you're a child?
You have red bone marrow when you'er young and you replace it with yellow blood marrow when you an adult.
Bone marrow is the spongy tissue that fills the inside of your bones. Red bone marrow helps make blood cells and yellow bone marrow helps store fat.
True or false:
The radius and the ulna are both in the forearm
True!
The forearm (found in between the elbow and the wrist) holds two important bones. Those two important bones are the radius and the ulna. The radius and the ulna connect to help you move your arm. Together, the two bones play a major role in how the forearm rotates. The radius houses a few muscles like your biceps and other tendons and ligaments that we will get into later. The ulna is the thinner and longer of the two bones in the human forearm and it joins with the humerus on its larger end to make the elbow joint.
The humerus is part of your upper arm (between the elbow and shoulder). The humerus is the base to which many muscles are placed. Because it connects at the _______ with a rotational joint, the humerus is important in supporting many of the arm's functions.
(a) arm part
(b) shoulder
(c) cranium
(b) Shoulder
The tibia is one of the bones inside the leg of humans. What other bone is paired to the tibia in the leg?
(a) Ebuoli
(b) bibula
(c) fibula
The fibula
The Fibula is one of the bones paired inside the leg of humans. The fibula connects to the much thicker bone, the tibia. The lower part forms part of the ankle joint, allowing for strength in movement. This is due to the fibula's major role as an point for the various muscles and ligaments of the leg and ankle.
True or False:
Ears are made completely of bone
False
Most of the ear is made of cartilage. Cartilage is a type of tissue that connects to other tissues and organs. Cartilage is also flexible. A regular bone isn’t flexible, but hard. Your nose is not a bone, but cartilage.

Skeleton
The skeletal system maintains homeostasis by creating new red blood cells as the old ones die off. It also helps maintain the level of calcium in the blood stream in your body.
True or False:
The tibia is known as the shin bone.
True!
The lower leg is made up of two types of bones, the tibia and the fibula. Also known as the shin bone, the tibia is the stronger and larger of the two leg bones. The most powerful muscles that move the foot and lower leg are connected to the tibia.
The ____ are made up of long, curved bones connected to spine. The ___cage is made up of twenty four bones (twelve on each side) and are perfectly in order. The ____ protects the lungs, heart, and other important organs in your chest. What is the missing word?
(a) legs
(b) lungs
(c) ribs
(c) Ribs
The phalanges are found in two places of your body, where are they.
(a) fingers and toes
(b) eyes and ears
(c) none of the above
(a) fingers and toes
The human wrist and hand (and toes) are made up of three different bone groups. One of those groups is the phalanges. The phalanges also have apical tufts, which are flat expansions of bone. The tufts hold the fingernails on the back side of the fingers, and the fleshy pad of skin on the palm side of the fingers.
True or False:
Adults have more bones than babies
False!
Babies have around 300 bones and adults have around 206 bones! As babies grow, some of their bones fuse together. Some children's bones are made of cartilage that is slowly replaced by hard bone as the baby grows.
The shoulder is the part of your body that moves the most. One of the bones that connect to the shoulder is the clavicle. Which is also known as the ______ ____. Fill in the blank for the two missing words.
