What else can I help you with?
When your cells need energy they send signals to your brain how do these signals make you feel?
When your cells need energy, they release a signaling molecule called adenosine which can make you feel tired or fatigued. This signals your brain to increase alertness and activity to supply more energy to the cells.
What is the name of the cells in the brain?
Neurons are the name of the cells in the brain that transmit information through electrical and chemical signals.
What transmitte messeges to the brain?
Nerves and brain cells in the brain send electric signals to each other to tell the body what to do.
What is the job of nerve cells?
Branching cells, know as nerve cells shape make them great for communication signals between the brain and the rest of the body. Branching cells great length helps these signals reach the brain quickly.
You can feel the prick of a pin because specialized nerve cells in the skin relay information to your?
brain via electrical signals. When a pin pricks your skin, it activates these nerve cells, sending signals to your brain to register the sensation of pain.
What happens when sound vibrations bend hairs on cochlear?
When sound vibrations cause the hairs on the cochlea to bend, this activates sensory cells which then stimulate nerve cells to send signals to the brain. The brain processes these signals as sound, allowing us to hear.
Why do you have brain cells and what are they for?
Brain cells, or neurons, are specialized cells that transmit information in the brain through electrical and chemical signals. They play a crucial role in processing and transmitting information, enabling functions such as thoughts, emotions, memory, and movement. The complex network of brain cells allows for the brain to carry out its functions and adapt to different stimuli.
What two cells in the retina of the eye detects light and send signals to the brain?
The two primary types of cells in the retina that detect light and send signals to the brain are rods and cones. Rods are responsible for vision in low light and are highly sensitive to light, while cones function in brighter light conditions and are responsible for color detection and detail. Both types of cells convert light into electrical signals, which are then transmitted to the brain via retinal ganglion cells.
How does the sense of smell communicate with the brain?
Olfactory cells act as sensors Transmit signals via the nervous system to the brain
How do ear hair cells contribute to the process of hearing?
Ear hair cells play a crucial role in the process of hearing by converting sound waves into electrical signals that the brain can interpret. These specialized cells detect vibrations in the inner ear and transmit signals to the brain, allowing us to perceive and understand sounds.
What are receptor cells in the lobes of the brain?
Receptor cells in the brain are specialized neurons that respond to specific types of stimuli, such as light, sound, or chemical signals. They are primarily located in sensory areas of the brain, including the occipital lobe (vision), temporal lobe (hearing), and parietal lobe (touch). These cells play a crucial role in processing sensory information, translating it into neural signals that the brain interprets to form perceptions of the environment.
How does damage to cochlear hair cells lead to the development of tinnitus?
Damage to cochlear hair cells can lead to the development of tinnitus because these cells are responsible for converting sound vibrations into electrical signals that the brain interprets as sound. When these cells are damaged, they can send faulty signals to the brain, resulting in the perception of sound when there is no external sound present, leading to tinnitus.
