Do some neurons lack an axon and communicate only with adjacent neurons?
If they are neurons they have an axon, some cell types do communicate using gap-junctions. Yes, some complex sensory organs ( in the retina and organ of Corti for example) do not have axons. These cells liberate transmitter from their soma directly onto postsynaptic neurons in proportion to the membrane potential change they experience.
What is the connection between sensory nerves and the neurons in the brain?
Sensory nerves transmit information from sensory receptors in the body to the neurons in the brain. When sensory receptors detect stimuli such as touch, temperature, or pain, they send signals through sensory nerves to the brain. Neurons in the brain then process and interpret these signals, allowing us to perceive and respond to the sensory information.
What is the change in responsiveness of the sensory system based on the average level of surrounding stimulation?
sensory adaptation
Which sequence best describes the change in signals as sensory neurons in the eye respond to an external stimulus?
The sequence typically involves the conversion of external stimulus (light) into electrical signals by photoreceptor cells in the retina. These signals then pass through the optic nerve to the brain, where they are processed and interpreted, resulting in the perception of visual information.
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
Nerve messages from motor nerve cells control the actions of muscles?
Yes. Sensory neurons sense a change in the stimulus and alert the interneurons located in the brain which send an impulse to the motor neurons to make the muscle contract.

What is environmental change?
Environmental change is when the environment goes under changes such as climate which animals have to adapt to.

How your brain and sensory organs get information from the outside world?
Your brain has about 100 billion neurons, all of which are interneurons. Each of these neurons may receive up to 10,000 messages from other neurons and may send messages to about 1,000 more. Every day, billions of nerve impulses travel through your nervous system from neuron to other neurons or body structures. The place where a neuron transfers an impulse to another structure is called a synapse. At the axon tips, electrical signals carried through the neuron change into a chemical form. This change allows the message to cross the gap. The message then continues in electrical from through the next neuron.
What is environmental elasticity?
Environmental elasticity is the responsiveness of demand for a product to a change in the environmental impact of the product.
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
What do nerves do?
A neuron is like a relay switch - it receives signals from other neurons and depending on the nature of the signals, the neuron may then 'fire' a signal of its own, stay silent, or become inhibited. This is like binary code - i.e.,"on" and "off" states. A neuron can oscillate between these states in a variety of frequencies. So the range of computations that even a single neuron can perform is impressive. Now, consider that this sort of thing is happening billions of times every second all throughout the nervous system and you can intuitively grasp just how complex the patterns of signals would become. In fact, somewhere in those patterns is what we would call our 'mind' and our 'intelligence' and so on. And this is all because of a large collection of neurons (~100 billion at birth) relaying signals to each other through a multitude of pathways (trillions).
When you change the number of neurons of an atom what else changes?
Neurons are nerve cells in the body but if you meant neutrons nothing normally happens; it sometimes increases radioactivity.
How does energy change from one form into another inside an animal?
Because the positively charged neurons in the animal's urine mixes with the negatively charged neurons, causing the energy to change.
