Sensation. This process involves the sensory organs detecting stimuli from the environment and converting them into neural signals that can be processed by the brain.
Muller's doctrine of specific nerve energies states that the nature of a sensation is determined not by the stimulus itself, but by the specific nerve fibers that are stimulated. In other words, different nerve fibers are responsible for transmitting different types of sensory information to the brain, regardless of the type of stimulus. This theory helped to establish the concept of sensory coding in neuroscience.
The brain is the central hub of the nervous system, responsible for processing and interpreting sensory information, making decisions, and sending out commands to the rest of the body through the spinal cord. It controls various functions such as movement, thinking, and emotions by sending and receiving electrical signals between neurons. Overall, the brain plays a crucial role in coordinating all activities of the nervous system.
Comparative: more nervous Superlative: most nervous
The superlative of "nervous" is "most nervous."
Sensation is defined as the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
Sensation. This process involves the sensory organs detecting stimuli from the environment and converting them into neural signals that can be processed by the brain.
The nervous system works with the endocrine system to create a response to a stimulus. The nervous system detects the stimulus and sends signals to the endocrine system, which releases hormones that help regulate the body's response to the stimulus. Together, these systems coordinate a response to the stimulus.
The nervous system sends signals to the proper areas of the body in response to a stimulus. Sensory receptors detect the stimulus and send the information as electrical impulses through neurons to the brain, which then processes the information and coordinates a response.
In very general terms the functions are Sensation via the afferent fibres and Control (of movements) via the efferent fibres.
The detection and encoding of stimulus energies by the nervous system is called sensation. Principles first recognized by Gestalt psychologists indicating that the brain imposes order on incoming stimuli are called perceptual grouping rules.
The olfactory epithelium, located in the upper part of the nasal cavity, is responsible for receiving the stimulus for smell. It contains specialized sensory neurons that detect odor molecules in the air.
Fundamentally the system involved in a reaction to a stimuli is the nervous system.

A functional property of nervous tissue called irritability is the ability to respond to a stimulus and convert it into a nerve impulse.
