RossNeurons communicate through electrochemical signals, known as action potentials, that allow them to relay information to other neurons. When a neuron stimulates another neuron, it triggers the release of neurotransmitters that can excite or inhibit the activity of the receiving neuron, influencing its firing potential. This communication is key in coordinating various functions in the brain and nervous system.

Why do neurons have branched endings?
Neurons have branched endings, called dendrites, to receive signals from other neurons and transmit them towards the cell body. This branching allows neurons to integrate incoming signals from multiple sources and perform complex computations. The more branches a neuron has, the greater its capacity to communicate with other neurons.
What do neurons stimulate?
Neurons stimulate other neurons or target cells (such as muscle cells or gland cells) through the release of neurotransmitters at synapses. This stimulation can trigger a response in the target cell, leading to activities such as muscle contraction or hormone release.
How do the types of neurons found in the CNS and pns differ in their function?
Sensory (afferent) neurons conduct sensory information toward the CNS.The brain and spinal cord contain interneurons. These receive information and if they are sufficiently stimulated, they stimulate other neurons.Motor neurons (efferent neurons) send information from interneurons to muscle or gland cells (effectors).
Where is the synaptic bulb found?
The synaptic bulb is found at the end of axon terminals in neurons. It is the structure responsible for releasing neurotransmitters to communicate with other neurons or target cells at a synapse.
What are neuron cell shaped like?
Neurons are shaped like long thin cells with a cell body, dendrites that receive signals, and an axon that transmits signals to other neurons. They have a unique branching structure that allows them to communicate with other neurons in the nervous system.
