What is the difference between the axial and appendicular skeleton?
The axial skeleton consists of the skull, spine, and ribcage, while the appendicular skeleton consists of the arms, legs, pelvic and shoulder girdle.
The human skeleton consists of ______ bones in an adult.

False
Yellow bone marrow produces white and red blood cells.
False
The axial skeleton includes the pectoral girdles and lower limbs.
False
Ligaments connect muscles to bones.
False
The skeletal system does not play a role in blood cell production.
False
What is the total number of bones in an adult human skeleton?
206
Which bone produces white and red blood cells, and platelets?
Red bone marrow
What is the function of ligaments in the skeletal system?
To connect bones to other bones
Which part of the skeletal system consists of the pectoral girdles, the upper limbs, the pelvic girdle, and the lower limbs?
Appendicular skeleton
What is the function of the spinal column in the skeletal system?
To protect internal structures
What are the two types of bone marrow and what do they produce?
The two types of bone marrow are yellow and red. Yellow bone marrow produces fat, bone, and cartilage, while red bone marrow produces white and red blood cells, and platelets.
How many bones are in the adult human skeleton?
There are 206 bones in the adult human skeleton.
What are the major bones of the human body?
The major bones of the human body include the skull, mandible, clavicle, sternum, pelvis, femur, tibia and fibula, humerus bone, radius and ulna, and the hand (27 bones).
What are ligaments and what is their function in the skeletal system?
Ligaments are fibrous connective tissue that connect bones to other bones in the body. Their function is to provide stability to joints.
What is the difference between the axial and appendicular skeleton?
The axial skeleton consists of the skull, spine, and ribcage, and has a total of 80 bones. The appendicular skeleton consists of the pectoral and pelvic girdles, as well as the upper and lower limbs, and has a total of 126 bones. The axial skeleton protects internal structures and is the origin of most muscles, while the appendicular skeleton plays a key role in movement and is the insertion point of most muscles.
