The fluid outside the axon contains a high concentration of Na and negatively charged proteins The correct option is.

. Sodium channels are inactivated. The axoplasm of the axon contains which of the following. Voltage-gated potassium channels open and potassium moves out of the cell initiating repolarization.

In contrast the fluid outside the axon contains a low concentration of K a high concentration of Na and thus form a concentration gradient. In contrast the fluid outside the axon has a high concentration of Na ions and thus forms a concentration gradient. The axoplasm contains an accumulation of modified mitochondria as well as a few lysosomes.

A length of the axon B presence or absence of a myelin sheath C diameter of the axon D presence or absence of nodes E whether or not the impulse begins in the CNS 79 The axoplasm of the axon contains which of the following. Which of the following is not a recognized structural classification for neurons. In contrast the fluid outside the axon has a high concentration of Na ions and thus forms a concentration gradient.

The fluid outside the axon contains a low concentration of K a high concentration of N. Absolute refractory period is the period when the cell is incapable of generating action potential. Why CNS neurons cannot regenerate.

The myelin sheath decreases the resistance of the axonal membrane to the flow of charge. These ionic gradients across the resting membrane are maintained by. The myelin sheath increases the insulation along the entire length of the axon.

As a result the axoplasm inside the axon contains a high concentration of K and negatively charged proteins and low concentration of Na. During this period voltage-gated Na channel undergoes conformational change from i _____. The axoplam inside the axon contains low concentration of Na III.

The myelin sheath decreases the speed of action potential conduction. The fluid outside the axon contains a low concentration of K IV. The axoplasm of the axon contains which of the following.

During the resting state the axoplasm inside the axon contains a high concentration of K and negatively charged proteins and a low concentration of Na In contrast the fluid outside the axon contains a low concentration of K a high concentration of Na and thus forms a concentration gradient. The axoplasm of the axon contains which of the following. Sodium channels regain their normal properties.

This leads to the ii _____ propagation of action potential from axon to axon terminus. This type of swelling appears to result from a damming up of axoplasmic flow causing the axon to become very swollen. B Isolated axoplasm did not incorporate 3Hleucine into proteins.

A graded depolarization brings an area of an excitable membrane to threshold. In a resting nerve fibre axoplasm contains a high concentration of K and negatively charged proteins and low concentration of N a. The following are the main steps in the generation of an action potential.

Sodium channels regain their normal properties. It is devoid of ribosomes associated to the reticulum but may contain ribonucleoprotein complexes especially during development. A graded depolarization brings an area of an excitable membrane to threshold.

This chemical moves across the cleft and attaches to chemo-receptors present on the membrane of the dendrite of next neuron. The axoplasm contains thin elongated mitochondria numerous cytoskeletal elements and transport vesicles. Consequently the axoplasm inside the axon contains high concentration of K ions.

All of the above. A The axon does not contain a significant amount of ribosomes or ribosomal RNA. In contrast the fluid outside axon contains a low concentration of K and a high concentration of Na and thus forms a concentration gradient.

The most abundant class of a neuron in the central nervous system is. Most CNS neurons lack centrioles. The following are the main steps in the generation of an action potential.

Solve any question of Photosynthesis In Higher Plants with-. The axoplasm inside the axon contains high concentration of K and negatively charged proteins II. Which of the following is not a recognized structural classification for neurons.

Consequently the axoplasm inside the axon contains high concentration of K and negatively charged proteins and low concentration of Na. A anaxonic B bipolar C multipolar D pseudopolar E unipolar. Vesicles mitochondria neurofibrils neurotubules The cytoplasm that surrounds the nucleus of a neuron is called the.

14 Identify the structure labeled 5 A axons B telodendria C dendritic spines D synaptic terminals E axosomata 15 The structure labeled 2 is a A cell body. Sodium channels are inactivated. Consequently the axoplasm inside the axon contains high concentration of K ions.

Consequently the axoplasm inside the axon contains a high concentration of K and negatively charged proteins and a low concentration of N a. The following evidence indicates that the labeled axonal proteins are not synthesized within the axon itself. When an impulse reaches at the end plate of the axon vesicles consisting of a chemical substance or neurotransmitter such as acetylcholine fuse with the plasma membrane.

A neurotubules B mitochondria C vesicles D neurofibrils E All of the answers are correct. Voltage-gated potassium channels open and potassium moves out of the cell initiating repolarization. Use Figure 11-1 to answer the following questions.

This ionic gradient is maintained by N a - K pump.
