- Which bone articulates proximal with innominate bone to form hip joint
- femur
- Which bone aticulates distally with tibia and patella to from knee
- femur
- anterior proximal lateral view of femur
- Greater trochanter Lesser trochanter Inter trotanteric line - joins them Femeral Head at the top - ball for joining Femeral Neck - between femoral shaft
- anterior proximal distal view of femur
- Lateral condyle - Lumps at bottom lateral - outside condyle Medial condylee- inside - protrudes more
- posterior aspect of femur
- Linea spira Medial supercondylar ridge Lateral supracindylar ridge - outside - lateral condyle - supra = above
- femoral head
- Hemispheroidal – large range of motionSmooth articular surfaceArticulates with the acetabulum
- femoral neck
- Inferio-lateral to femoral headJoins femoral head to femoral shaftSurface characterised by many grooves and ridges
- femoral shaft
- Gentle anterior convexityAnterior, medial and lateral aspects smoothgives strength fall down without it
- Examples of long bones
- Femur, tibia, fibula, metatarsals, phalange
- Example of short bones
- tarsal bones
- Example of flat bones
- Parietal bone in skul
- Example of irregular bones
- Maxilla
- Examples of sesamoid bones Where do they sit
- Patella, sesamoid bones of 1st metatarsalSit within a tendon
- Examples of bones in axial skeleton
- Skull, vertebral column, ribs and costal cartilage, sternum
- What is the appendicular skeleton
- Bones of the upper and lower limbs
- What is a tubercle/processes and name their function
- rough area of bone, attachment point for ligaments, muscles and maintains the course of a tendon
- What is a tendon What is a ligament
- Tendon - fibrous tissue that connects skeletal muscle to bone Ligament - fibrous tissue that connects bones to other bones
- Structure of long bones
- 2 ends, head and base joined together by bone shaft in the middle
- Structure of short bones
- cuboid shape
- What type of bone are vertebrae
- irregular small bones that make up the spine
- What bones comprise the pelvis
- Innominate bones (left, right)sacrumcoccyx
- why is the spine curved
- provides strength
- What does vertebrae allow
- Protection of spinal cord
- How does the vertebrae help you move
- Small incremental movement in many joints - allows for larger movement like bending
- Whereabouts is cervical vertebrae numbers
- near top of neck C1-C7
- whereabouts is thoracic vertebrae located numbers
- neck lower, backT1-T12
- whereabouts is lumbar vertebrae numbers
- lower backL1-L5
- Function of the pelvis
- Holds lower abdominal organs
- innominate bones composition in the pelvis
- Illium, Ischium and pubis
- What is the innominate bone joined to posteriorly
- sacrum
- What is the innominate bone joined to anteriorly
- pubic synthesis
- Where does the innominate bone articulate with in the pelvis
- Articulates with the femur at the acetabulum
- Function of acetabulum
- holds the head of the femur to join the hip bone
- What is the acetabulum comprised of
- The fusion of the illuminati, ischium and pubis to form the innominate bone
- What is a concave structure
- curves in the way
- What is a convex structure
- Curves out of the way
