1 Structure of the Skeletal System. P1

2 Structure of the Skeleton We know that the 206 bones of the skeleton are split into two different groups… The Axial Skeleton – 80 bones The Appendicular skeleton – 126 bones

3 The central core of the body or its AXIS. Consists of: Skull The vertebrae The sternum The ribs It provides the core from which the limbs hang from.

4 The parts/ limbs hanging off of the AXIAL skeleton. Shoulder Girdle (scapula/ clavicle) Pelvic Girdle Upper and Lower limbs

5 Task… Axial SkeletonAppendicular Skeleton List the below Bone names into the relevant column in the table below… Answers!! Location of major bones: Cranium Clavicle Ribs Sternum Humerus Radius Ulna Scapula Ilium Pubis Ischium Carpals & Metacarpals & Phalanges Femur Patella Tibia Fibula Tarsals & Metatarsals Vertebral column – (cervical, thoracic, and lumbar vertebrae, sacrum, coccyx) Location of major bones: Cranium Clavicle Ribs Sternum Humerus Radius Ulna Scapula Ilium Pubis Ischium Carpals & Metacarpals & Phalanges Femur Patella Tibia Fibula Tarsals & Metatarsals Vertebral column – (cervical, thoracic, and lumbar vertebrae, sacrum, coccyx)

6 Task: Match the EVERY DAY name for each bone, with its correct ANATOMICAL name.

7 Task!! In pairs: 1 person labels the other as a ‘human skeleton’. Making labels for ALL of the various bones that we have learned thus far. You also need to be to know ‘both’ names for each bone.

8 Major bones of the body explained… PROTECT Consists of 8 bones fused together to PROTECT your brain. 14 other facial bones that form the face and jaw…

9 Flat bone in the middle of your chest shaped like a dagger. PROTECTS ATTACHMENT PROTECTS the heart and acts as an ATTACHMENT point for the ribs and clavicle

10 Adults have 12 pairs of ribs, that run between sternum and thoracic vertebrae. PROTECTIVE Ribs are flat bones that form a PROTECTIVE cage around the HEART and LUNGS. True Ribs False Ribs Floating Ribs

11 Provides a point of attachment for many muscles of upper arm and back. correct distance The role of the Clavicle is to keep the scapula the correct distance from the sternum One end is connected to the sternum and the other to the scapula Situated on the upper back of the body

12 Humerus Radius Ulna The Humerus, Radius and Ulna all form the ELBOW joint. In order for the hand to move, the Radius moves across the ulna…

13 Consists of 3 area, made up of different kind of bone. Phalanges - 14 bones Meta-Carpels Carpels- 8 bones

14 ILLIUM, PUBIS and ISCHIUM Consists of 3 bones fused together- ILLIUM, PUBIS and ISCHIUM PROTECT Function: to PROTECT the lower internal organs… such as the bladder, reproductive organs and when pregnant the developing foetus!

15 Consists of 4 bones: FEMUR, FIBULA, TIBIA and PATELLA Femur: Femur: Longest bone in the body and forms the knee joint with the TIBIA Tibia: Tibia: The weight bearing bone of the lower leg Fibula Fibula : The non-weight bearing bone of the lower leg and helps form the ankle. Patella Patella : Bone that floats over the knee and lie within the patella tendon and SMOOTHES the movement of the tendons over the knee.

16 Tarsals, Metatarsals Phalanges Consists of 3 areas: Tarsals, Metatarsals and Phalanges Tarsals- 7 bones 3 Phalanges in each toe… apart from the big toe that has 2 -5 Bones

17 7 Cervical vertebrae make up the neck and runs to the shoulders 12 Thoracic vertebrae make up the chest area 5 Lumbar vertebrae make up the lower back 5 vertebrae which are fixed together make the Sacrum. Coccyx is 4 bones fused together, remnants from when we had a tail!

18 Long Bone Short Bone Femur Humerus Tibia Metacarpals Phalanges Having a body longer than it is wide and having growth plates at either end (epiphysis) They are approximately wide as they are long Function of Protection and Stability, with little movement Flat Bones Flat bones are strong, flat plates of bone with the main function of providing protection to the bodies vital organs and being a base for muscular attachment. Scapula (shoulder blade). The Sternum (breast bone), Cranium (skull), Pelvis and Ribs are also classified as flat bones

19 Irregular Bones Sesamoid Bones These are bones that do not fit into any other category due to their unusual shape. Good examples being the Vertebrae, Sacrum and Mandible (lower jaw). Sesamoid bones are usually present in a tendon where it passes over a joint, acting as protection to the tendon. The most obvious example: The Patella (knee cap) which sits within the Patella or Quadriceps tendon. Sesamoid bones are usually short or irregular bones, imbedded in a tendon.

20 1) Learners must describe the axial and appendicular skeleton. 2) The different types of bone in each of the skeletons and be able to locate all of the named bones stated in the Unit content (List). 3) They must also describe the function of the skeletal system. 1) Learners must describe the axial and appendicular skeleton. 2) The different types of bone in each of the skeletons and be able to locate all of the named bones stated in the Unit content (List). 3) They must also describe the function of the skeletal system. Types of bone: Long bones, Short bones, Flat bones, Irregular bones, Sesamoid bones Types of bone: Long bones, Short bones, Flat bones, Irregular bones, Sesamoid bones Functions: Support Protection Attachment for skeletal muscle Source of blood cell production Store of minerals Functions: Support Protection Attachment for skeletal muscle Source of blood cell production Store of minerals Location of major bones: Cranium Clavicle Ribs Sternum Humerus Radius Ulna Scapula Ilium Pubis Ischium Carpals & Metacarpals & Phalanges Femur Patella Tibia Fibula Tarsals & Metatarsals Vertebral column – (cervical, thoracic, and lumbar vertebrae, sacrum, coccyx) Location of major bones: Cranium Clavicle Ribs Sternum Humerus Radius Ulna Scapula Ilium Pubis Ischium Carpals & Metacarpals & Phalanges Femur Patella Tibia Fibula Tarsals & Metatarsals Vertebral column – (cervical, thoracic, and lumbar vertebrae, sacrum, coccyx)
