Anatomy Muscle disorders

By Penny Dunning

Multiple Choice

A few hours after a person or animal dies, the skeletal muscles contract causing joints to stiffen and become locked in place. This stiffening is called

• livor mortis.

• algor mortis.

• rigor mortis.

• myo-mortis.

Multiple Choice

A tendon may become painfully inflamed and swollen following an injury or the repeated stress of athletic activity. 

• Muscle Strain

• Tendinitis

• Fracture

• Sprain

Multiple Choice

Muscle fibers are flexible, but they can tear if overstretched. This is called:

• Muscle strain

• Tendinitis

• Sprain

• Fracture

Multiple Choice

Caused by an antibody against the acetylcholine receptor

• Fibrodysplasia ossificans progressiva (FOP)

• Myasthenia gravis

• Rhabdomyolysis

• Amyotrophic Lateral Sclerosis

Multiple Choice

A common pseudonym is "lock jaw"

• Cerebral palsy

• Tetanus

• Botulism

• Rotator cuff tear

Multiple Choice

The risk of contracting this disease is high in individuals who are not up to date on their vaccinations

• Botulism

• Tetanus

• Cerebral palsy

• Myasthenia gravis

Multiple Choice

Can be acquired by stepping on a rusty nail

• Myasthenia gravis

• ALS

• Cerebral palsy

• Tetanus

Multiple Choice

Myasthenia Gravis

• The lack of voluntary control of muscle movement.

• Decrease in size of normal developed muscle tissue

• Defective growth of the muscles and skeletal system

• Muscle disorder caused by the lack of acetylcholine

• extremely sleepy, weak and lack energy

Multiple Choice

65% occur in infants or children younger than 1 year of age, typically the result of exposure to contaminated soil, or by eating foods that contain botulism spores.

• True

• False

Multiple Choice

A toxin produced by a type of bacteria called Clostridium botulinum interferes with the release of the neurotransmitter Acetylcholine.

• True

• False

Multiple Choice

A progressive neurodegenerative disease where the motor nerves that provide voluntary movements and muscle control atrophies or wastes away

• ALS or Lou Gehrig's disease

• Duchenne muscular dystrophy

• tetanus

• myotonia congenita

• myasthenia gravis

Multiple Choice

A delayed relaxation of the skeletal muscles after voluntary contraction, electrical stimulation, or even being startled.

• ALS or Lou Gehrig's disease

• Duchenne muscular dystrophy

• tetanus

• myotonia congenita

• myasthenia gravis

Multiple Choice

Causes cholinesterase to not break down the acetylcholine in the synapse. This results in a person's muscles contracting and not relaxing

• ALS or Lou Gehrig's disease

• Duchenne muscular dystrophy

• tetanus

• myotonia congenita

• myasthenia gravis

Multiple Choice

The body produces antibodies that attack receptors for the neurotransmitter acetylcholine on skeletal muscle cells at neuromuscular junctions.

• ALS or Lou Gehrig's disease

• Duchenne muscular dystrophy

• tetanus

• myotonia congenita

• myasthenia gravis

Multiple Choice

Caused by the chronic and incurable death of motor neurons

• Rotator cuff tear

• Botulism

• Dermatomyositis

• Amyotrophic lateral sclerosis (ALS)

Multiple Choice

Pseudonym is Lou Gehrig's Disease

• ALS

• Myathenia gravis

• Botulism

• Cerebral palsy

Multiple Choice

A progressive neurodegenerative disease where the motor nerves that provide voluntary movements and muscle control atrophies or wastes away

• ALS or Lou Gehrig's disease

• Duchenne muscular dystrophy

• tetanus

• myotonia congenita

• myasthenia gravis

Multiple Choice

Muscles progressively get weaker, often resulting in inability to walk, talk or breathe. Occurs in boys (sex-linked inheritance pattern)

• ALS or Lou Gehrig's disease

• Duchenne muscular dystrophy

• tetanus

• myotonia congenita

• myasthenia gravis

Multiple Choice

Caused by a botulinum toxin released by the Clostridium botulinum bacteria

• Rotator cuff tear

• Botulism

• Cerebral palsy

• Tetanus

Multiple Choice

Can be caused by contaminated canned foods or raw honey

• Tetanus

• Botulism

• Myasthenia gravis

• Rotator cuff tear

Multiple Choice

Classified as a neuromuscular blocking agent—it produces flaccidity in skeletal muscle by competing with the neurotransmitter acetylcholine at the neuromuscular junction

• Strychnine

• Curare & poison dart frogs

• Cyanide

• ALS

Multiple Choice

Lowers the threshold level for an action potential, making it more likely the muscles will contract

Death occurs from convulsions and asphyxia

Used in rat poisoning

• Strychnine

• Curare & poison dart frogs

• Cyanide

• ALS

Multiple Choice

Botox injections use a toxin called onobotulinumtoxinA to temporarily prevent a muscle from moving. This toxin is produced by the microbe that causes botulism

• True

• False

Multiple Choice

65% occur in infants or children younger than 1 year of age, typically the result of exposure to contaminated soil, or by eating foods that contain botulism spores.

• True

• False

Multiple Choice

A toxin produced by a type of bacteria called Clostridium botulinum interferes with the release of the neurotransmitter Acetylcholine.

• True

• False
