23
Q

Low Blood, Low Oxygen, Low Nerves

A

Cerebral Infraction (stroke)

24
Q

Mild Stoke

A

Transient ischemic Attack

25
Q
  • Direct Physical between
    cells= GAP JUNCTIONS.
  • Direct signal transaction
  • Occurs in CNS and Heart
  • Rare
A

Electrical

26
Q
  • Space between two cells
  • Signal transduction via NT
  • Most Common
A

Chemical

27
Q
  • Catalyze breakdown of ATP
    regenerated by creatine phosphate.
  • Creatinine- “kidney”
A

Enzyme ATPase

28
Q
  • For contraction
  • Build muscle or increase size.
  • There must be anaerobic respiration
A

Oxygen

29
Q

Enough oxygen

A

Aerobic Respiration

30
Q
  • Oxygen debt (deficiency)
  • Then it will produce lactic acid that is
    responsible for pain
  • May lead to muscle fatigue or
    inability to contract
  • Prolonged muscle contraction leads
    to muscle fatigue.
A

Anaerobic Respiration

31
Q

minimal stimuli
needed to cause contraction

A

Threshold stimulus

32
Q

increase muscle size due to
workload.

A

Hypertrophy

33
Q

decrease muscle size

A

Atrophy

34
Q

increase muscle size due to
hormones

A

Hyperplasia

35
Q

removal of the breast.

A

Mastectomy

36
Q

37
Q
  • Movable ends
  • Pulled towards the origin with
    contraction
A

Insertion

38
Q
  • A stiff neck the occur in SCM
A

TORTICOLLIS

39
Q
  • Make action
  • Prime movement
  • Contraction
A

Agonist

40
Q
  • Opposite action
A

Antagonist

41
