Skeletal System Basics
This is the number of bones found in the adult human skeleton
What is 206?
This is the largest bone in the human body.
What is the femur?
The femur belongs to this classification of bone.
What is a long bone?
The elbow is an example of this type of joint.
What is a hinge joint?
This tough band of connective tissue connects muscle to bone.
What is a tendon?
This mineral is the primary mineral found in bones.
What is calcium?
This small bone is located at the front of the knee joint.
What is the patella?
Carpals in the wrist belong to this classification of bone.
What are short bones?
This joint type between the first two vertebrae of the neck allows you to rotate your head.
What is a pivot joint?
This strong band of connective tissue connects bone to bone and helps stabilize joints.
What is a ligament?
Protection, movement, blood cell production, and support are four major examples of these.
What are the functions of the skeletal system?
This bone attaches the sternum to the shoulder.
What is the clavicle?
The sternum, ribs, and scapula all belong to this classification of bone.
What are flat bones?
The joint where the femur meets the pelvis is an example of this type.
What is a ball-and-socket joint?
These are the two major divisions of the human skeletal system.
What are the axial and appendicular skeletons?
This soft material found inside bones is where red and white blood cells are produced.
What is bone marrow?
Of the two bones in the lower leg, this one is the larger.
What is the tibia?
Vertebrae and hip bones belong to this classification because of their complicated shapes.
What are irregular bones?
Found at the base of the thumb, this type of synovial joint allows movement in multiple directions.
What is a saddle joint?
This division of the skeleton contains 80 bones and includes the vertebral column, much of the skull, and the rib cage.
What is the axial skeleton?
This process explains why humans go from around 300 bones at birth to about 206 bones as adults.
What is bones fusing together?
This is the smaller of the two forearm bones and is located on the lateral side of the forearm.
What is the radius?
The patella belongs to this classification of small, round bones that develop within tendons.
What are sesamoid bones?
In this type of synovial joint, an oval-shaped bone surface fits into an oval-shaped depression, allowing movement in two directions.
What is an ellipsoid joint?
Of the three structural joint types discussed in class, this one is freely movable and contains fluid that reduces friction between bones.
What is a synovial joint?
