Question

How are neurons similar to other cells? How are they unique?

a) Similarity: Neurons have a nucleus; Unique: Neurons lack axons
b) Similarity: Neurons undergo mitosis; Unique: Neurons can conduct electrical impulses
c) Similarity: Neurons have cell membranes; Unique: Neurons lack neurotransmitters
d) Similarity: Neurons have no connections to other cells; Unique: Neurons have a rigid structure

Answer 1

Neurons are similar to other cells in having a cell body and a cell membrane. However, they are unique in having specialized structures such as dendrites and axons, and in their ability to conduct electrical impulses and transmit neurotransmitters at synapses.

Step-by-step explanation:

Neurons are similar to other cells in that they have a cell body (soma) that contains a nucleus and other cellular components. They also have a cell membrane like other cells. However, neurons are unique in several ways:

1. Neurons have specialized structures called dendrites that receive messages from other neurons at synapses. Some neurons have multiple dendrites, while others do not have any.
2. Neurons have a long tail called an axon, which can be wrapped in an insulating layer called myelin. This allows neurons to conduct electrical impulses.
3. Neurons have specialized structures called synapses, which are the gaps between nerve cells where neurotransmitters transmit the electrical impulse.
