◉ What makes up the final part of the axial skeleton? Answer: the
thorax
the sternum
12 pairs of ribs.
◉ What makes up the appendicular skeleton? Answer: the bones of
the girdle and limbs
◉ What bones make the upper appendicular skeleton? Answer:
pectoral & shoulder girdle
clavicle
scapula
upper extremities
◉ What are the bones of the arm? Answer: Humerus
Radius
Ulna
,Carpals (wrist bones)
Metacarpals (hand bones)
phalanges (finger bones)
◉ What bones make the lower part of the appendicular skeleton?
Answer: The pelvic girdle or os coxae
◉ What bones make the os coxae? Answer: fused ilium
ischium
pubis
◉ What bones make up the lower extremities? Answer: femur
tibia
fibula
tarsals (ankle bones)
metatarsals (foot bones)
phalanges (toe bones)
◉ How do muscles make movement? Answer: Contraction in
response to nervous stimulation.
, ◉ What occurs in muscle fibers during contraction? Answer: Myosin
& actin filaments slide together.
◉ What structures make up muscle cells? Answer: Myofibrils made
up of sarcomeres.
◉ What must be present for a muscle cell to contract? Answer:
Calcium and ATP
◉ What does nervous stimulation from motor neurons cause in the
muscles? Answer: Release of calcium ions from the sarcoplasmic
reticulum.
◉ What is the function of calcium in muscle contraction? Answer:
Attach to inhibitory proteins on the actin filaments of the muscle
cell, moving them aside.
This forms cross bridges between actin and myosin filaments.
◉ Why are the skeletal muscles of the muscular system considered
voluntary? Answer: Because they are under conscious control.
◉ How do skeletal muscles work? Answer: In pairs: the prime mover
and the antagonist.
