The type of neuron that has one main dendrite and one main axon is called a bipolar neuron. These neurons are typically found in sensory systems, such as in the retina of the eye and the olfactory system. Bipolar neurons play a crucial role in transmitting sensory information from receptors to the central nervous system. Their structure allows for efficient signal processing and transmission.
What else can I help you with?
Describe parts of the neuron?
The neuron consists of three main parts: the cell body or soma, dendrites, and an axon. The cell body contains the nucleus and other organelles. Dendrites receive incoming signals from other neurons, while the axon carries signals away from the cell body to transmit to other neurons.
The most common type of neuron found in the central nervous?
The most common type of neuron found in the central nervous system is the multipolar neuron. These neurons have many dendrites and a single axon extending from the cell body. Multipolar neurons are involved in processing and transmitting information in the brain and spinal cord.
Which type of cell is composed of one dendrite and one axon and is found in the eye and nose a. pseudo-unipolar neuron b. Schwann cell c. bipolar neuron d. multipolar neuron?
bipolar neuron
What does the structure of a neuron look like?
There are three types of Neurone and a different structure for each. Each of these types has all the same part just in a different arangement. They have a part callled the Axon which is where they send their Action Potentials (impulses) down, parts called Dendrites which is the heavily branched part where they receive stimulationfrom and a part inbwetween called the Cell Body which is where the Nucleus is. We will look at them in the order they would come in a complex reflex arc. Firstly the Sensory Neurone: This type of cell has dendrites that are out on a stalk from the cell body. These dendrited are specialised to activate neurone when a specific stimulation type is present. The axon from this cell type is usually not so long as in motot neurones but substantially longer than in interneurones. The cell body sits roughyl in the middle ot the two branches (the axon and the dendrite branches). Secondly the Interneurone: This types of cell are what is mostly found in the brain. They have incredibly branched dedrites making them look very like a tree. Their axons may or may not be branched and their length OS also very variable. Finally the Motor Neurone: Here the cell body and the dendrites are very close together, infact the dendrites brach directly of from the cell body. The axon in a cell of this type is usually very long and not very branched at all. This part will be connected to another neurone to pass the singal (in the form of an action potential) on to whatever organ is to be affecteed.
Is it true that motor neurons pass messages from neuron to neuron?
Yes, an electrical signal is passed from the dendrites of 1 motor neuron, through it's cell body, through it's axon (the long tail looking feature of the neuron). It then travels through branches of the axon and forms synapses with other motor neurons, this is how the electrical signal is passed.
What type of neuron has many dendrites?
multipolar neuron
What is the part of a neuron which acts as a tiny antennae and conducts signals toward the axon of that cell?
Dendrites are the part of a neuron that act as tiny antennae and receive signals from other neurons. These signals are then conducted toward the cell body and, if the signal is strong enough, passed along to the axon of the neuron.

What is a type of neuron with only two dendrites?
The type of nearon with only two dendrites is bipolar.
The most type of neuron in the human body is?
Multipolar neurons This is the most common type of neuron, with one axon and many dendrites. Multipolar neurons are so-named because they have many (multi-) processes that extend from the cell body: lots of dendrites plus a single axon. Functionally, these neurons are either motor (conducting impulses that will cause activity such as the contraction of muscles) or association (conducting impulses and permitting 'communication' between neurons within the central nervous system).

An action potential in the axon terminal of a motor neuron opens what type of ion channels?
Exocytosis
Which type of cell is composed of one dendrite and one axon and is found in the eye and nose a. pseudo-unipolar neuron b. Schwann cell c. bipolar neuron d. multipolar neuron?
bipolar neuron
Chemical substance released at the axon terminals are called?
the signals are known as Action pottential. and the chemical substances or signal molecules are known as Neurotransmiters
What might a neuron have?
Neurons have lots of things. They have the usual cellular apparatus, a membrane, a nucleus, mitochondria, etc. They can also have some distinctive neuron type structures, which are axons and dendrites.
What is the relationship between a neurone and a nerve?
neuron = cell body + dendrites + axons nerve = axon + schwann cells (peripheral nervous system only) equivalent term of nerve in the central nervous system is called tracts neuron is a type of cell nerve is an anatomical term
