The musculoskeletal system is made up of the
body’s bones (the skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue
that support and bind tissues and organs together. The skeleton serves as the main storage system for calcium and phosphorus.
What are 6 main functions of the skeletal system?
It is composed of 270 bones at birth and decreases to 206 bones by adulthood after some bones have fused together. The human skeleton serves six major functions:
support, movement, protection, production of blood cells, storage of ions, and endocrine regulation
.
What are the 6 functions of the skeletal system quizlet?
The six main functions of the skeletal system are:
Support, protection, assistance in movement, mineral homeostasis (storage and release)
, blood cell production (red bone marrow) and triglyceride storage (yellow bone marrow).
What are the main parts of a skeleton?
The skeleton is traditionally divided into two major parts:
the axial skeleton and the appendicular skeleton
, both of which are pictured in Figure 14.2. 3. The axial skeleton forms the axis of the body. It includes the skull, vertebral column (spine), and rib cage.
What are the 6 parts of the skeletal system?
- The skull protects the brain.
- The vertebrae protect the spinal cord.
- The rib cage, spine, and sternum protect the lungs, heart and major blood vessels.
Do females have more bones than males?
In the majority of populations,
men have larger and stronger bone
and joint surfaces, and more bone at muscle attachment sites. However, women have stronger pelvises because of their distinct ability to carry a child and experience childbirth.
What is the longest bone in the human body?

.
What organs are in skeletal system?

What type of skeleton do humans have?
The human skeleton is
an endoskeleton
that consists of 206 bones in the adult. It has five main functions: providing support to the body, storing minerals and lipids, producing blood cells, protecting internal organs, and allowing for movement.
What are the three main functions of skeletal system?
The skeletal system works as a support structure for your body. It gives
the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals
.
What are the functions of the skeleton quizlet?
The five important functions of the skeletal system are
support, protection, movement, mineral storage, and blood cell formation
. Without our skeleton, our bodies would have no definite shape. The skeleton protects the internal organs.
What is the relationship between muscle function and bones?
Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly onto each other.
Muscles contract to move the bone attached at the joint
.
What are the 2 types of bones?
- Long bone – has a long, thin shape. Examples include the bones of the arms and legs (excluding the wrists, ankles and kneecaps). …
- Short bone – has a squat, cubed shape. …
- Flat bone – has a flattened, broad surface. …
- Irregular bone – has a shape that does not conform to the above three types.
What are the 2 types of skeleton?
The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions:
axial skeleton and appendicular skeleton
.
Are teeth part of the skeleton?

considered part of the skeleton system
even though they are not bone. Teeth are the strongest substance in your body being made up of enamel and dentin. There are 32 teeth in an adult, and 28 in children. In looking at bone and teeth, there can and is genetic variation between individuals.
