Guided Notes – Musculoskeletal System

SC.6.L.14.5 Identify and investigate the general functions of the major systems of the human body (musculoskeletal) and describe ways these systems interact with each other to maintain homeostasis.

Skeletal Systems

1. ____________________skeleton – the skull, vertebrae, and ribs which

supports and protects the internal organs.

2. _____________________Skeleton – the arms, legs, shoulders and

pelvis

3. _________________________ – the tough, flexible strand of

connective tissue that holds bones together

4. ____________________________ – a strong, flexible and smooth

connective tissue found at the end of bones that allow them to move

smoothly

Bones are made of…

› ___________________________ – dense and hard, no visible open

space

› ____________________________ – provides most of the strength and

support for the bone, has many open spaces

› _____________________________ – bone cells that deposit calcium

› _____________________________– connective tissue that allows the

bone to be a little flexible

› _______________________________ – soft tissue at the center of

bones

Two types of marrow

› ___________________ marrow – makes red and white blood cells, in

the center of flat bones

› ___________________ marrow – stores fat, in the center of long

bones

5 types of bone connections or joints

› ______________________________– the place where two or more

bones connect

› __________________________________– found in the skull and

allow no movement between bones

› __________________________________ – allow movement of the

bones

› ___________________________________ – allows one of the bones

to rotate in a large circle

› _____________________________________ – allows flexibility in the

wrist and ankles

› _____________________________________ – allow bones to move

back and forth

Bone Growth

Draw your osteocyte cell

› ___________________________ – locations where long bones

lengthen

› ___________________________ – bone cells that move into cartridge

and harden it into bone

Bone Injuries and disorders

› _____________________________ – bones that are broken

› ______________________________ – injuries to a ligament cause by

stretching the joint to far

› _______________________________ – a disease that causes bone to

become thin and weak

› _______________________________ – a disease that causes joints

to stiffen, swell and become painful
