The pacemaker of the heart is the SA (sinoatrial) node. Located in the right atrium, it generates spontaneous electrical impulses at 60-100 beats per minute, initiating each heartbeat. It has the highest intrinsic firing rate, making it the natural pacemaker.

Black urine can be associated with several conditions:

  • Bilirubinuria: The presence of bilirubin in urine can lead to dark urine, although it is typically more yellow-brown than black.
  • Blackwater fever: This is a severe complication of malaria that can cause hemolysis and dark urine due to the presence of hemoglobin.
  • Alkaptonuria: This is a rare genetic disorder where homogentisic acid accumulates in the body, leading to dark urine upon exposure to air.

Myotonic dystrophy is a unique myopathy because it primarily affects the distal muscles first (e.g., in the hands, feet, face, and neck), unlike the other options provided which are all known to primarily involve the proximal muscles (e.g., shoulders, hips, and thighs).

Polymyositis causes inflammation and weakness in the proximal muscles.

Spinomuscular atrophy (SMA) is a motor neuron disease leading to progressive proximal muscle weakness and atrophy.

Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive proximal muscle weakness and wasting.

Myotonic dystrophy is the exception as it typically presents with distal weakness and myotonia (delayed muscle relaxation).
