The Skeletal System provides us with many important functions. It provides us with the shape and form for our bodies as well as supporting‚ protecting‚ allowing our body to move freely‚ producing blood for the body‚ and storing minerals. The Skeletal System is the system of our body that gives our body its physical shape and with the help of the Muscular System it keeps us moving and makes us able to do tasks that we don’t think about like raising our leg to kick a football or using our legs to boost

Joints and Movements The Joints Definition: A joint (articulation) is point of contact between bones or between bone and cartilage. Joint Classifications Joints are classified by: The degree of movement they allow The structure of the joint The three types of joints that we will look at are: 1. Fibrous joints 2. Cartilaginous joints 3. Synovial joints Fibrous Joints These joints are also called "fixed" or "immoveable" joints‚ because they do not move. These joints have no joint cavity

bones might shift which causes an abnormally shaped spine. There are also many physical deformities of scoliosis as well as pain and complications in the digestive or respiratory system. Physical deformities may include uneven shoulders‚ hips‚ or scapula (shoulder blades)‚ or unevenly spaced arms. These physical deformities cause many patients to not fit in normal clothes correctly.

glands. The brachial plexus carries out these functions in the pectoral girdle and upper limbs. Specifically‚ nerves of the brachial plexus aid in innervation of the muscles of the upper limbs (with the exception of the trapezius and the levator scapula. In addition to muscular innervation‚ these nerves also innervate most of the cutaneous membrane of the upper limb (with the exception of the axilla‚ a point on the superior portion of the shoulder‚ and the dorsal scapular area). The nerves of the

Chapter 5: The Skeletal System I. Introduction. The skeletal system consists of the bones‚ along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints. A. Functions of the Skeleton. 1. The skeleton supports the body. 2. The skeleton protect soft body parts. The skull protects the brain‚ the rib cage protects the heart and lungs‚ and the vertebrae protect the spinal cord. 3. The skeleton produces blood cells. Red bone marrow contains

specifically‚ humans and apes really aren’t so different compared to other living species. Some specific physical similarities between both is how the rib cage is very broad from left to right and it’s shallow from the front and back. Both have dorsally scapula and shoulder joints facing the same way giving them that mobility. Now‚ shifting to more of the brain development‚ humans and apes have some similarities in this area. Many scientists believe that the human and ape brain evolved unusually rapidly
