Structures of the

Skeletal System:

·

· Joint-two bones that come together at a joint, which vary

in type, allows for movement

· Cartilage- a tough but flexible tissue that covers the ends

of bones

· Ligament- connective tissue that binds one bone to

another.

· Tendons- connective tissues that attaches to the bone.

Aides in movement of bone or structure.

2. striated muscle · (skeletal muscle)-moves all bones, controls facial expressions, and eye movements.

3. smooth muscle · (visceral muscle) lines the walls of the internal organs,

such as the intestines.

4. cardiac muscle · (unique) is a combination of striated and smooth muscle.

5. central nervous

system

6. peripheral nervous system

7. Respiratory system key structures and organs

8. upper respiratory tract

(brain and spinal cord)- messages travel through the

spinal cord to the brain, and the brain in response directs

all functions for the body

consists of all nerves outside the brain and spinal cord.

They relay messages between the CNS and other areas

of the body, including sensory organs.

· consists of lungs, passageways for air flow, blood vessels, and muscles.

· They work together to bring oxygen into the body and

expel carbon dioxide, that is produced during metabolism.

· Lungs-primary organ- which exchange gases (oxygen

and carbon dioxide) during breathing.

nose, pharynx (throat), and larynx (voice box)

9. lower respiratory · trachea, (windpipe), bronchial tree, and lungs
