Most CNS neurons lack centrioles.

. Which of the following is not a recognized structural classification for neurons. Absolute refractory period is the period when the cell is incapable of generating action potential. The fluid outside the axon contains a low concentration of K a high concentration of N.

Synapse cell body soma telodendria collaterals cell body soma 11 The axoplasm of the axon contains which of the following. Why CNS neurons cannot regenerate. A graded depolarization brings an area of an excitable membrane to threshold.

The axoplasm of the axon contains which of the following. Which of the following is not a function of the nervous system. During this period voltage-gated Na channel undergoes conformational change from i _____.

Sodium channels are inactivated. Sodium channels are inactivated. These ionic gradients across the resting membrane are maintained by.

This chemical moves across the cleft and attaches to chemo-receptors present on the membrane of the dendrite of next neuron. Neurotubules mitochondria neurofibrils vesicles All of the answers are correct. The axoplasm contains thin elongated mitochondria numerous cytoskeletal elements and transport vesicles.

The most abundant class of a neuron in the central nervous system is. Voltage-gated potassium channels open and potassium moves out of the cell initiating repolarization. 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.

A large swollen myelinated axon with a diameter of about 6 microns in the fornix of a 30 year old rhesus monkey. Solve any question of Photosynthesis In Higher Plants with-. A The axon does not contain a significant amount of ribosomes or ribosomal RNA.

The axoplasm contains an accumulation of modified mitochondria as well as a few lysosomes. In contrast the fluid outside axon contains a low concentration of K and a high concentration of Na and thus forms a concentration gradient. This type of swelling appears to result from a damming up of axoplasmic flow causing the axon to become very swollen.

Vesicles mitochondria neurofibrils neurotubules The cytoplasm that surrounds the nucleus of a neuron is called the. A anaxonic B bipolar C multipolar D pseudopolar E unipolar. It is devoid of ribosomes associated to the reticulum but may contain ribonucleoprotein complexes especially during development.

In contrast the fluid outside the axon contains a low concentration of K a high concentration of Na and thus form a concentration gradient. The following are the main steps in the generation of an action potential. In contrast the fluid outside the axon has a high concentration of Na ions and thus forms a concentration gradient.

The axoplasm inside the axon contains high concentration of K and negatively charged proteins II. 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. This ionic gradient is maintained by N a - K pump.

Use Figure 11-1 to answer the following questions. The fluid outside the axon contains a high concentration of Na and negatively charged proteins The correct option is. As a result the axoplasm inside the axon contains a high concentration of K and negatively charged proteins and low concentration of Na.

This leads to the ii _____ propagation of action potential from axon to axon terminus. The axon hillock connects the axon with the _____. The fluid outside the axon contains a low concentration of K IV.

The axoplam inside the axon contains low concentration of Na III. In a resting nerve fibre axoplasm contains a high concentration of K and negatively charged proteins and low concentration of N a. In contrast the fluid outside the axon has a high concentration of Na ions and thus forms a concentration gradient.

In contrast the fluid outside the axon contains a low concentration of K a high concentration of Na and thus form a concentration gradient. 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. B Isolated axoplasm did not incorporate 3Hleucine into proteins.

The axoplasm of the axon contains which of the following. Consequently the axoplasm inside the axon contains high concentration of K and negatively charged proteins and low concentration of Na. Sodium channels regain their normal properties.

All of the above. The axoplasm of the axon contains which of the following. 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.

Sodium channels regain their normal properties. A graded depolarization brings an area of an excitable membrane to threshold. Consequently the axoplasm inside the axon contains a high concentration of K and negatively charged proteins and a low concentration of N a.

A neurotubules B mitochondria C vesicles D neurofibrils E All of the answers are correct. Which of the following is not a recognized structural classification for neurons. Voltage-gated potassium channels open and potassium moves out of the cell initiating repolarization.

The following are the main steps in the generation of an action potential. Consequently the axoplasm inside the axon contains high concentration of K ions.
