During microscopic analysis of a biopsy, a pathologist notes multinucleated cells with peripherally pushed nuclei. If a genetic mutation prevented the formation of these specific cell structures during embryogenesis, the immediate biological consequence would be:

A. Inability to regulate blood pressure
B. Inability to propel food through the digestive tract
C. Inability to perform voluntary skeletal movements
✓
D. Inability to pump blood through the pulmonary circuit

📝 Explanation

The described cells are skeletal muscle fibers, characterized by being syncytial (multinucleated) with nuclei at the periphery. Their primary function is voluntary movement. Loss of this tissue would prevent somatic motor functions, leaving autonomic functions intact.

📖 Additional Information

  • Inability to regulate blood pressure
  • Inability to propel food through the digestive tract
  • Inability to perform voluntary skeletal movements
  • Inability to pump blood through the pulmonary circuit
