Introduction to The Skeleton
Role of the skeleton:
Locomotion/support
Two fundamental divisions of skeleton
Skeleton
o Axial skeleton
Support and protection
E.g. skull protects brain
vertical column protects spinal cord
rib cage protects heart + lung + kidneys
80 bones along the longitudinal axis
o Appendicular skeleton
Locomotion
arms and legs
Added on to main body: for walking etc
Joints between bones
o different types of joints, depending on types of connective tissue
Muscles move bones by acting on joints
o muscles have to cross joints to be able to work, cannot just cross bone alone
o muscles motivated by nerves: sense movement
Nerves make muscles move
o Afferent nerves:
sensory neurons that carry nerve impulses from sensory stimuli towards the
central nervous system and brain
o efferent nerves
motor neurons that carry neural impulses away from the central nervous
system and towards muscles to cause movement
Axial skeleton
Skull
, Ribs, sternum
vertebrae
More in children, some bones fuse (in joints)
Cage extends to protect liver and kidneys
Know main bones, and sutures: frontal bones, coronal suture,
Many bones inside skull as well
Brain floats in small amount of cerebral spinal fluid
Sections of brain:
o Frontal
o middle
o posterior
