skeletal

Cards (56)

  • axial bones - provide protection on vital organs, stability, attachment for muscles
  • appendicular bones - provide support and mobility
  • axial bones - cranium, ribs, sternum and vertebral column
  • support function - provides support for organs, something for them to attachment and suspend to, axial skeleton is the basis for all movement
  • shape - gives you shape eg shape of your face and how tall you are
  • protection - protects vital organs by absorbing impact used by flat bones
  • movement - skeletal system moved by formation of bones and joints and attatchments to muscular system via tendons
  • fixed joints allow no movement, they allow us to grow and develop
  • cartilaginous joints allow small movement
  • synovial bones are freely moveable and theres 6 types
  • fixed joint examples cranium and pelvis
  • cartilaginous joint examples ribs, vertebrae, sternum
  • synovial examples hip, knee, ankle
  • blood cell production contains bone marrow where red blood cells and white blood cells are made
  • mineral storage iron, calcium and phosphorus are stored in bones, uses for functions such as nerve transmissions, haemoglobin and metabolism
  • long bones are longer than it is wide, provides movement, mineral storage, support, blood cell production
  • examples of long bones are femur, tibia, humerus, metacarpals, metatarsals
  • short bones are as wide as they are long, provides support, fine movement and weight bearing
  • short bones examples are carpals and tarsals
  • flat bones are flat plates of bone, provides protection. base for all muscular attachments and blood cell production
  • flat bone examples are pelvis, sternum, scapula, cranium, ribs
  • sesamoid bones are short and irregular embedded in a tendon, provides protection and support
  • sesamoid bone examples are the patella
  • irregular bone has an odd shape provides movement, protection and support
  • irregular bone examples are vertebrae and mandible
  • ball and socket examples are hip and shoulder
  • ball and socket movements are flexion, extension, abduction, adduction, circumduction and rotation
  • hinge movements are flexion and extension
  • hinge examples are knee and elbow
  • condyloid movements are flexion, extension, abduction, adduction and rotation
  • condyloid examples are wrist
  • pivot movements are rotation
  • pivot examples are neck and radio-ulna
  • saddle movements are flexion, extension, abduction and adduction
  • saddle examples are thumb
  • gliding movements are glide
  • gliding examples are vertebrae
  • articular cartilage is hard and smooth, has a glossy consistency, covers ends where bone meet. prevents friction between bones
  • ligaments are very strong and slightly elastic. they hold two ends together ensuring stability whilst allowing movement
  • synovial membrane is a layer that lines the synovial joint and produces synovial fluid
