Examlex
A bone marrow specimen is received in the cytogenetics lab. FISH analysis has been ordered. The laboratician performs the assay and notices that 96% of the patient's cells contain both 5q- and 12q- deletions. These cytogenetic findings are characteristic of:
Smooth Muscle Contraction
The involuntary process by which smooth muscles found in the walls of internal organs contract and relax, controlled by the autonomic nervous system.
Myosin Phosphatase
An enzyme that plays a critical role in muscle relaxation by dephosphorylating myosin light chains.
Hyperpolarization
An increase in the membrane potential of a cell, making it more negative and less likely to fire an action potential.
Resting Membrane Potential
The electrical charge difference across the plasma membrane when a neuron or muscle cell is at rest.
