A neurone consists of a cell body and two types of nerve fibre which are branches extended from the cytoplasm of the cell body. The two nerve fibres are dendrons which transmit nerve impulses towards the cell body and axons which transmit nerve impulses away from the cell body.

The human nervous system consists of two parts—central nervous system and periphery nervous system. The central nervous system consists of the brain and the spinal cord. The periphery nervous system consists of cranial nerves and spinal nerves, wherein the former is responsible for linking the receptors and effectors in the head and the next to the brain, and the latter is responsible for linking the receptors and effectors in the rest of the body to the spinal cord

The nervous system consists of the central nervous system and the peripheral nervous system.

The central nervous system consists of the brain and the spinal cord.

The peripheral nervous system consists of cranial nerves, which link receptors and effectors in the head and the neck to the brain, and spinal nerves, which link receptors and effectors in the rest of the body to the spinal cord.

The nervous system is made of of neurones

Due to the movement of ions across cell membrane, it creates an electrical potential when the neurone is stimulated

The most important part of the nervous system is:

Central nervous system

includes the brain and spinal cord only.

Peripheral nervous system

Consists of :
cranial nerves
spinal nerves

Group 5

s21102920 — 2025-10-13 04:12:11 UTC

Human nervous system consists of two parts which are central nervous system and peripheral nervous system.

As for central nervous system, it consists of brain and spinal cord.

As for central nervous system, cranial nerves and spinal nerves are consisted. Cranial nerves refer to the nerves which link receptors and effectors above the neck, whilst spinal nerves link receptors and effectors in the rest of the body to the spinal chord.

There are two nerve systems.They are central & periphery nerve systems. The central nerve system include brain and cord while periphery nerve system include cranial nerves and spinal nerves

Have fat cell wrap around nerve fibre, forming a insulating layer to speed up transmission of nerve fibre

Grp 3 G

s21109423 — 2025-10-13 04:13:04 UTC

Myelination is fat cells (Schwann cells) which covers the dendrons and axons. It acts as an insulator to prevent transmitting the nerve to the surroundings and speeds up the transmission of the nerve impulses.

Group 4

s211048_46 — 2025-10-13 04:13:09 UTC

a neurone consists of two parts:

A cell body and nerve fibres

There is two types of nerve fibre

Dendrons :transmit nerve impulses toward cell body

Axons:transmit nerve impulses away from cell body

And there is some fat cell called myelin sheath wrapping around the nerve fibre

Grp 6

s21111627 — 2025-10-13 04:13:18 UTC

There are sensory neurones , interneurones and motor neurones. Neurone consists of cell body and nerve fibres. Nerve fibres include dendrons which transmit nerve impulses towards the cell body and axons which transmit nerve impulses away from the cell body.

The signals is electrochemical in nature, meaning the signals are having two nature - electric in nature and chemical in nature.

For Electric in nature, it is due to the movement of positively charged ions leading to the movement of electrons, creating the electrical messages transmitted along nerve fibres at high speed.

For Chemical signals, it refers to the transmission of neurotransmitters and ions like Na+ or Ca2+ between the synapse.

The reason why it has to be electrochemical in nature is that there are synapses between neurons which stops the transmission of electrical signals, hence there is a need for the chemical in nature.

Grp 5

s21101224 — 2025-10-13 04:13:30 UTC

Nerve impulses are electrical messages transmitted along nerve fibres at high speed, but they cannot travel directly from one neurone to another because there is synapse between neurones . The electrical messages are the flows of positively charged ions in our body.

s21102528 — 2025-10-13 04:13:32 UTC

Nerve impulses are the electrical messages transmitted along the nerve fibres. When the nerve impulses arrives at the synaptic knob, neurotransmitter ( a chemical ) is released. When they are bind to specific protein receptors on the membrane of the next neurone, it stimulates the dendron or the cell body to generate a nerve impulse. Therefore, the signals transmitted are electrochemical in nature.

Gp 6

s21107319 — 2025-10-13 04:13:34 UTC

When the signal is being transmitted in nerve cells, it is transmitted as an electrical impulse. When the electrical signal reaches the end of the nerve cell, it facilitates the release of neurotransmitters, which is chemical signal. These chemicals cross the synaptic gap between cells and pass the signal on to the next cell.

So, the whole process alternates between electrical and chemical signals.

Nerve impulses are electrical messages that be transmitted along nerve fibres at a high speed. They are transmitted towards the cell body through dendrons and transmitted away from the cell body through axons.

Nerve impulses is electrical messages and it is electrochemical in nature .Transmitted in high speed through neurones(dendrons and axons) throughout the body

Group 4

Nerve impulses are electrical messages transmitted along nerve fibres at high speed. However, nerve impulses cannot travel directly from one neurone to another because there is a narrow gap between two neurones. It’s the flow of electrons.

s211082_39 — 2025-10-13 05:03:24 UTC

Nerve impulses are electrical signals transmitted along nerve fibers at high speed,which cannot travel directly from one neurone to another because there is a narrow gap between neurones called synapse.

Nerve impulses are electrical message transmitted along nerve fibres at high speed. However, nerve impulse cannot travel directly from one neuron to another because there is a narrow gap called synapse

Group 4

s211048_46 — 2025-10-13 12:33:27 UTC

The nerve fibre is covered by myelin sheath which formed by fat cells，it is a insulating layer that allows nerve impulses to transmit quickly along the nerve fibre.
