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, 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.

Excretion is a natural process that helps animals, humans and other organisms to expel out the waste products (urea and uric acid) from the body. This waste product is generated inside the body during metabolism. Cells need energy and nutrients to survive. To get the required energy, they perform certain biochemical reactions. These reactions take place and some byproducts are also produced. This byproduct can be very toxic or lethal to the cells if allowed to accumulate inside the body. This waste product is get rid of by the process of excretion. The main excretory organ in humans are as follows: Skin: Remove excess salt in the form of sweat from the body. Lungs: Remove carbon dioxide that is generated during respiration. Kidney: Remove nitrogenous waste from the body.
