Nervous Tissue: The Neuron
Scelta multipla
In a typical neuron, what is the soma?
A
The insulating covering formed by glial cells that increases the speed of impulse conduction
B
The cell body that contains the nucleus and most organelles and serves as the neuron's main metabolic center
C
The long, single process that conducts action potentials away from the cell body
D
The branched processes that primarily receive incoming signals from other neurons
Guida verificata passo dopo passo1
Step 1: Understand the structure of a typical neuron, which includes the soma, dendrites, axon, and myelin sheath.
Step 2: Identify the soma as the part of the neuron that contains the nucleus and most of the organelles.
Step 3: Recognize that the soma serves as the neuron's main metabolic center, responsible for maintaining cell health and function.
Step 4: Differentiate the soma from other parts: dendrites receive signals, the axon conducts impulses away, and the myelin sheath insulates the axon.
Step 5: Conclude that the soma is the cell body of the neuron, housing the nucleus and organelles essential for metabolic activities.
