How many axons does a neuron have? How many bones are in the thoracic cage? How many organs are in the excretory system? What is the difference between the insect tracheal system and the mammalian trachea? How many vertebrae make up the human vertebral column?
If the cell body dies, the neuron dies. Axon . This long, cablelike projection of the cell carries the electrochemical message (nerve impulse or action potential) along the length of the cell. Depending upon the type of neuron, axons can be covered with a thin layer of myelin sheath, ...
Axons: These long, thin, cable-like projections of the cell carry electrochemical messages (nerve impulses or action potentials) along the length of the cell. Depending upon the type of neuron, axons can be covered with a thin layer of myelin, like an insulated electrical wire. Myelin is mad...

one neuron often has inputs from many presynaptic neurons—some excitatory and some inhibitory—so IPSPs can cancel out EPSPs and vice versa. It is the net change in postsynaptic membrane voltage that determines whether the postsynaptic cell has reached its threshold of excitation needed to fire ...
This skull elongation is sometimes associated with Neandertal variants that are located near the genes UBR4 and PHLPP1, which are involved in neuron production and the formation of myelin, the fatty sheath that insulates the axons of larger neurons, allowing them to communicate more reliably over...
They can also directly affect neurotransmitter activity at the synapses between neurons. Oligodendrocytes: provide structural support to the axons of neurons through a process called myelination. They produce a substance called myelin, which makes up an insulating sheath around axons that allow them to...
A microscopy image of DishBrain where fluorescent markers show different types of cells: neurons and axons are green, purple marks neurons, red marks dendrites, and blue marks all cells. Where multiple markers are present, colors are merged and typically appear as yellow or pink. ...
Depending upon the type of neuron, axons can be covered with a thin layer of myelin, like an insulated electrical wire. Myelin is made of fat, and it helps to speed transmission of a nerve impulse down a long axon. Myelinated neurons are typically found in the peripheral nerves (sensory...
