Charcot-Marie-Tooth disease (CMT) is a heritable condition characterized by weakness in leg, foot, and hand muscles. CMT causes the myelin sheaths and axons to degenerate in the peripheral nervous system. An individual diagnosed with CMT has difficulty holding a cup because: O a. The myelin in the motor neurons is damaged thereby preventing an impulse from moving along the axon O b. The dendrites in the motor neurons are damaged thereby preventing an impulse from moving along the axon O c. The dendrites in the sensory neurons are damaged thereby preventing an impulse from moving along the axon O d. The myelin in the sensory neurons is damaged thereby preventing an impulse from moving along the axon

Clear my choice Charcot-Marie-Tooth disease (CMT) is a heritable condition characterized by weakness in leg, foot, and hand muscles. CMT causes the myelin sheaths and axons to degenerate in the peripheral nervous system. An individual diagnosed with CMT has difficulty holding a cup because: O b. O a. The myelin in the motor neurons is damaged thereby preventing an impulse from moving along the axon The dendrites in the motor neurons are damaged thereby preventing an impulse from moving along the axon The dendrites in the sensory neurons are damaged thereby preventing an impulse from moving along the axon O d. The myelin in the sensory neurons is damaged thereby preventing an impulse from moving along the axon O c. A group of students decided to investigate the relationship between the mass of an object and the pain felt when the object hits a student's foot. They collect data for the pain felt when a glove, an eraser, and a cell Which of the following statement correctly explains why more pain is felt when the cell phone hits the student's foot? O a. The nerve impulses increase in strength, thereby making the maximum membrane potential higher than normal. The nerve impulses increase in strength and lower the threshold potential. O b. O C. The nerve impulses occur more frequently, thereby transmitting more action potentials according to the intensity of pain. The nerve impulses occur more frequently and prevent neurons from entering the refractory period. O d.
