Redraw the diagram. Name and label the parts indicated, below, Carries impulses away from the cell body

The neuron can be characterised as the structural and functional unit of the nervous system. It is composed of dendrons, soma, axon hillock, axon, and synaptic knobs. Axon can be characterised as the elongated fibre of the neuron that extends from the soma to the terminal endings and transmits the neural signal. This structure carries the impulses away from the cell body.

Redraw the diagram. Name and label the parts indicated, below, Branches of dendrons

The neuron can be characterised as the structural and functional unit of the nervous system. It is composed of dendrons, soma, axon hillock, axon, and synaptic knobs. Dendrites can be characterised as tree-like extensions found to be present at the beginning of the neuron. These structures receive information from other neurons and transmit electrical stimulation to the soma or the cell body of the neuron.

Observe the picture and answer the following question Name the part indicated as (i).

In the given diagram the axon is represented by (i). The neuron can be characterised as the structural and functional unit of the nervous system. It is composed of dendrons, soma, axon hillock, axon, and synaptic knobs. Axon can be characterised as the elongated fibre of the neuron that extends from the soma to the terminal endings and transmits the neural signal.

Redraw the diagram. Name and label the parts indicated, below, Secretes neurotransmitter

The neuron can be characterised as the structural and functional unit of the nervous system. It is composed of dendrons, soma, axon hillock, axon, and synaptic knobs. Neurotransmitters carry the neural or electrical signal across the synapse to other neurons. Synaptic knobs secrete the neurotransmitter.

Observe the picture and answer the following question How does myelin sheath form ?

The myelin covering is known as the myelin sheath and is broken up at points called the nodes of Ranvier. This structure plays an essential role in increasing the speed of the transmission of the signal. Some axons are covered with myelin which is a lipid substance and acts as an insulator. Myelin sheath is formed due to the repeated encircling of Schwann cells around the axon.
