What is a simple neural receptor?
A receptor (protein) on a neuron that receives stimulus (light, pressure, chemical...etc). The stimulus generates a receptor potential (local disturbance/slight depolarization in membrane potential).
The depolarization of a neural membrane creates a?
The depolarization of a neural membrane creates an action potential, which is a brief electrical charge that travels down the axon of a neuron. This action potential is crucial for transmitting signals between neurons and ultimately forms the basis of communication in the nervous system.
What does organ of Corti rest on?
The organ of Corti rests on the basilar membrane within the cochlea of the inner ear. This membrane is essential for detecting sound vibrations and transducing them into neural signals for the brain to interpret.
What Forms the floor of the cochlea?
The floor of the cochlea is formed by the basilar membrane, which is a thin, flexible structure that supports the hair cells responsible for detecting sound vibrations. The basilar membrane plays a crucial role in converting sound waves into neural signals that can be interpreted by the brain.
A basilar membrane would be found in?
The basilar membrane is found within the cochlea of the inner ear. It plays a crucial role in converting sound vibrations into neural signals that the brain can interpret as sound. The basilar membrane is a key component of the auditory system's process of hearing.

Muscle cells gland cells and specialized cells that respond to neural stimuli are called?
Muscle cells are called myocytes, gland cells are called secretory cells, and specialized cells that respond to neural stimuli are called neurons.
How would depressants affect the resting membrane potential?
the conduction of neural information to the muscle fiber

Which week of pregnancy is the neural tube is formed?
In the 3rd week of pregnancy called gastrulation, specialized cells on the dorsal side of the fetus begin to change shape and form the neural tube.
What are the functions of an integral protein found in the cell membrane?
The functions can vary greatly, the fact that its an integral protein limits the functions but there are still many different functions. Ill go through a few functions of integral transmembrane proteins. Transportation. Integral proteins can transport molecules and ions through the membrane, facilitated or active transport are two such transport functions. The protein can also act as ion channels which help the cells to keep the ion gradient at a good level (varies greatly for different ions). The protein can also act as receptors for different hormones or neural signals. The integral proteins can also be cytoskelleton, which function is to connect different cells to eachother, or they can be flagells, villi or microvilli.
Structure overlies the organ of Corti is the?
The organ of Corti in the cochlea is overlaid by the tectorial membrane. This membrane plays a crucial role in the transduction of sound waves into neural signals by interacting with hair cells in the organ of Corti. The tectorial membrane helps amplify sound vibrations and transmit them to the auditory nerve for processing.
How are neural impulses generated?
Neural impulses are generated when a neuron receives signals from other neurons or sensory receptors, causing a change in its membrane potential. This change in membrane potential triggers an action potential, a rapid electrical signal that travels down the axon of the neuron. This action potential then triggers the release of neurotransmitters at the synapse, allowing the signal to be passed on to other neurons.
What Forms the floor of the cochlea?
The floor of the cochlea is formed by the basilar membrane, which is a thin, flexible structure that supports the hair cells responsible for detecting sound vibrations. The basilar membrane plays a crucial role in converting sound waves into neural signals that can be interpreted by the brain.
What is a nerve membrane at rest called?
At rest, the nerve membrane is referred to as polarized, meaning there is a difference in electrical charge between the inside and outside of the cell. This difference is maintained by the sodium-potassium pump, which actively transports ions across the cell membrane.
A basilar membrane would be found in?
The basilar membrane is found within the cochlea of the inner ear. It plays a crucial role in converting sound vibrations into neural signals that the brain can interpret as sound. The basilar membrane is a key component of the auditory system's process of hearing.
