Muscular system diseases

wasting away of muscle tissue

• atrophy

• hypertrophy

• lactic acidosis

• unfused tetanus

Muscle fatigue is primarily due to a build-up of ______ during anaerobic respiration.

• acetylcholine

• ATP

• creatine phosphate

• lactic acid

NGSS.HS-LS2-3

occurs because there is no ATP to remove myosin cross bridges after death

• atrophy

• muscle spasms

• myotonic dystrophy

• rigor mortis

Inherited muscle-destroying diseases characterized by degeneration of individual muscle fibers (usually voluntary)

• Lactic acidosis

• Muscular dystrophy

• Myasthenia gravis

• Rigor mortis

NGSS.HS-LS3-1

autoimmune disease that attacks acetylcholine receptors leading to muscle weakness

• Moebius disease

• Muscular dystrophy

• Myasthenia gravis

• Sarin gas exposure

6th and 7th cranial nerve don’t develop; palsy on one (or both) side of face

• lactic acidosis

• Moebius disease

• Muscular dystrophy

• Myasthenia gravis

sudden, involuntary contraction of single muscle in large group

• fasciculation

• fibrillation

• spasm

• tic

muscles contract but have decreasing power to relax (become weak and waste away); symptoms more severe with each generation

• atrophy

• myasthenia gravis

• myotonic dystrophy

• rigor mortis

A ______ can be used to measure skeletal muscle contraction. (i.e. in the "chewing lab")

• cardiogram

• encephalogram

• myogram

• telegram

Sarin gas...

• inhibits acetylcholinesterase.

• inhibits the release of acetylcholine at the axon terminal.

• inhibits the release of Ca+2 in the muscle cell

• produces antibodies against acatylcholine receptors.
