Always contain Carbon
The majority of organic compounds contain carbon, hydrogen, and occasionally other elements such as nitrogen, sulfur, oxygen, or phosphorus.
<h3>What are Organic compounds ?</h3>
Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
- The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides.
- Carbon is the key element because it has four electrons in an outer electron shell that can hold eight electrons

Explanation:
Answer:
A sensory neuron.
Explanation:
The nervous system can be divided in two systems: the central nervous system and the peripheral nervous system. The central nervous system (CNS) is composed by the brain and the spinal cord. The peripheral nervous system (PNS) consists of the nerves and ganglia. Neurons are specialized cells that form the basic functional unit of the nervous system. There are three types of neurons: sensory, motor and interneurons. The sensory neurons are in charge of bringing signals into the CNS, and the motor neurons are in charge of carrying signals out of the CNS. The interneurons act as intermediaries, passing information between two neurons.
As the name implies, sensory neurons are activated by the senses, for example: sound, visible light, physical contact (heat and cold), chemical signals (smell and taste). The loss of sensation in one hand would be the result of a damaged sensory neuron.
the autonomic (involuntary) nervous system controls the rate at which the heartbeats. sympathetic (fight or flight) signals speed up the heart’s rate while parasympathetic (rest and digest) signals slow it down. The part or parts of the heart that forms sympathetic and parasympathetic neurons form synapses is called cardiac plexus.
Cardiac plexus is a plexus of the nerves that are present at the base of the heart and is divided into superficial and deep part. The sympathetic and the parasympathetic nerves form synapses with heart in the form of cardiac plexus.
The sympathetic nerves are responsible for activating flight or fight mode while parasympathetic nerves are responsible for restoring the normal body state.
