How are sensory neurones adapted to their function?
Sensory neurons are adapted to their function through specialized structures that enhance their ability to detect stimuli. They possess receptor endings that are sensitive to specific types of stimuli, such as light, sound, or pressure, allowing for the transduction of these signals into electrical impulses. Additionally, their long axons facilitate rapid transmission of information to the central nervous system, ensuring quick responses to environmental changes. The myelination of these neurons further increases conduction speed, optimizing the sensory processing of incoming information.
Which structures relays nerve impulses between the brain and sense organ?
The structures that relay nerve impulses between the brain and sense organs are the sensory neurons. These neurons transmit signals from the sense organs to the brain through the central nervous system. In the brain, the signals are processed and interpreted, leading to the perception of various sensory stimuli.
What receives stimuli and forms impulses?
Neurons receive stimuli from the environment or other cells, which triggers the formation of electrical impulses that travel along the neuron's axon. These impulses then allow for communication between different parts of the body or with other neurons.
What type of tissue is specialized for receiving stimuli and conducting impulses?
Nervous tissue is specialized for receiving stimuli and conducting impulses. Neurons are the primary cells of nervous tissue that are responsible for transmitting electrical signals throughout the body.
What are nerves carrying impulses from the sense organs called?
Sensory nerves, or the receptor nerves, as they are only made up of sensory neurons. Receptors are the specialised structures at the end of the sensory nerves that receive the stimuli and convert it into an electrical signal to be conducted by the nerve as a nerve impulse.
What type of neuron picks up stimuli from the external or internal environment and convert those stimuli to nerve impulses?
uit ykhfut di8hlik im gaaay
What sends impulses to brain?
sensory neurons
What is the defference between membrane irritability and membrane conductivity?
Irritablity is the ability to respond to stimuli and convert it to nerve impulses. Conductivity is the ability to transmit that impulse.
What is the work of neuron?
They transmit nerve impulses and stimuli.

What structures consists of self exciting tissue?
Self-exciting tissue structures include the heart's pacemaker cells in the sinoatrial node and the autonomic nervous system's neural circuits that regulate breathing and heartbeat. These structures can generate electrical impulses and trigger rhythmic activity without external stimuli.
What type of output energy are in all receptors?
The type of output energy in all receptors is electrical signals. Receptors convert various forms of stimuli, such as light, sound, pressure, or chemicals, into electrical impulses that can be interpreted by the nervous system.
What is the type of tissue that receives stimuli transmit impulses and controls the actions of the muscles and glands?
nervous tissue
What stimulates sensory impulses at receptors?
Sensory impulses at receptors are typically stimulated by specific environmental stimuli such as light, sound, touch, temperature, or chemicals. These stimuli activate specialized receptors on sensory neurons, which then generate neural signals that are transmitted to the brain for further processing and interpretation.
