2 The human skeleton consists of 206 bones. We are actually born with more bones (about 350), but many fuse together as a child growsbones support your body and allow you to movecontain a lot of calcium (an element found in milk, broccoli, and other foods)manufacture blood cells and store important minerals.
3 The longest bone in our bodies is The smallest bone is the stirrup bone inside the ear.HAMMER ANViL STiRRUPThe longest bone in our bodies isthe femur (thigh bone).
11 Cervical Vertebrae the first set of vertebral bones of the spine located beneath the skullthere are 7 cervical vertebrae consists of 7 vertebral bones, named the C1, C2, C3, C4, C5, C6, and C7.the primary function of the cervical vertebrae is protection of the spinal cord and support of the body.these vertebrae can flex and extend to allow for movement.generally smaller than the other vertebrae
12 Thoracic Vertebrae vertebrates beneath the cervical vertebrae the middle segment of the spineconsists of 12 bones called T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, and T12these bones increase in size and width from T1 to T12.larger than the cervical vertebrae but smaller than the lumbar vertebrae.houses the spinal cord and protects the spinal cord
13 Lumbar Vertebrae the third curve of the spine Beneath the thoracic vertebraeconsists of 5 bones – the L1, L2, L3, L4, and L5the largest vertebral boneseach individual bone increases infunction is the protection of the spinal cord.also allows for much of human body motionsupports much of the human body’s weight.
15 Bones are connected to other bones at joints many different types of joints:fixed joints (such as in the skull, which consists of many bones)hinged joints (such as in the fingers and toes)ball-and-socket joints (such as the shoulders and hips).
16 fixed joint is a joint between two bones that doesn’t move. a good example of this is in the skull - the skull plates don't move together or against each other, but they are connected or fused
17 Hinge joints are places in the human skeleton where the ends of bones meet and rotate examples of hinge joints in the human body are the elbow, the knee, the ankle, and the knuckles
18 The most range of movement by the joints is provided by a "ball-and- socket" joint which the spherical head of one bone lodges in the spherical cavity of anotherIn the shoulder joint, the humerus (upper arm bone) fits into the socket of the shoulder blade. Because the socket is shallow and the joint loose, the shoulder is the body's most mobile joint.
19 Gliding Joints"Gliding" joints permit a wide range of mostly sideways movements - as well as movements in one direction –a pivot joint near the top of the spine allows the head to swivel and bend. Other pivot joints, in the forearm and lower leg, allow the wrist and ankle to twist.
20 The Pelvic Bonesa ring-like structure of bones at the lower end of the trunk. The two sides of the pelvis are actually three bones (ilium, ischium, and pubis) that grow together as people age
21 Other BonesSCAPULAthe bone that connects the humerus (upper arm bone) with theCLAVICLE (collar bone).
22 Hyoid BoneA small, U-shaped bone situated centrally in the upper part of the neck, beneath the mandible but above the larynx near the level of the third cervical vertebraeThe hyoid is (uniquely in the vertebrate skeleton) not joined to any other bone but is suspended in position by muscles that connect it to the mandible
