Question

According to the neuron doctrine, the nervous system is made of neurons that connect with each other through 1. A. Interaction B. Channels C. Gap junction D. Synapses A typical neuron has three structures, soma, dendrite and axon. How are dendrites different from axons? 2. A. B. C. D. Each neuron has only one axon but could have many dendrites Dendrites have synaptic vesicles but axons have spines. Only axons can be depolarized All of the above 3. Which technique allows one to visualize axons and dendrites of neurons? A. Golgi staining B. Nissl staining C. Cajal's staining D. Hollingsworth's staining There is high [K+] but low [Na+] inside cells. How is this concentration gradient maintained by cells? 4. A. Voltage gated sodium channel B. Voltage gated potassium channel C. Sodium and potassium pump D. Both A and B When the brain is deprived of oxygen, the mitochondria within neurons cease producing ATP What effect would this have on the membrane potential eventually? Why? 5. The membrane potential will be the same because the membrane potential is established by facilitated diffusions and does not require energy The membrane potential will be zero because there won't be any net diffusion of ions The membrane potential will be higher because the sodium and potassium pumps will be affected The membrane potential will be lower because the sodium and potassium pumps will be affected A. B. C. D.

Explanation / Answer

1. Answer : (D) synapses

According to the neuron doctrine the nervous system is made of neurons that connect with each other through synapses.

Explaination : synapses are present at neuromuscular junction , i.e.1. where one neuron is connected to another neuron and 2 . where one neuron has to transfer it's information to a muscle spindle .
Synapses are of two types : Chemical synapses ( transmission is through chemical Neurotransmitter ( most commonly Ach) ) and Electrical synapses ( transmission is similar to a axon).
