In part, yes. The nerve cell is what ensures the message of an external or internal stimulus gets to the brain so we are consiously aware of that stimulus. However, in order for a nerve cell to get the message, it must receive an input from a receptor. As such, the receptors at the end of a nerve cell are the most directly responsible for our sensitivity. Some examples of the receptors are:
- nociceptors
- mechanoreceptors (meissners corpuscles, etc.)
- prorioreceptors (muscle spindles)
- chemoreceptors (taste buds)
What else can I help you with?
What does the size and shape of a cell tell us?
The shape of a cell may give us a clue about the function of the cell.
What organ system allows you to feel the heat?
there is no organ,it is the nerve cell that tells us what is hot and cold.it sends signals to your brain.
What cell in your skin allows us to sense pressure?
Merkel cells, located in the epidermis of the skin, are responsible for sensing light touch and pressure. They are connected to nerve endings and help transmit information about pressure stimuli to the brain.
How does calcium work to help us?
Calcium has at least 2 rules in the body. One is to stregnthen bones so that old people do not get curved backs (osteoporosis, bones with holes). When they are old. A more important rule of Calcium is to increae or decrease the transmission of a nerve impulse. Ca 2 + has a 2 plus charge. When a nerve inpulse arrives ina neuron (nerve cell), it had a negative charge. The nerve impulse is inside the nerve cell membrane. Ca 2 + will be outside the nerve cell membrane. Calcium of + charge will be attracted to the - charge of the nerve impulse. So Ca 2+ will cross the cell membrane into the nerve cell. The basic result is that a + charge crosses into the membrane towards a - charge. The Calcium 2 + is attracted to the nerve impulse made of electorn, a negative charge. A third neuron acting on the 1 st neuron can increase or decrease the transmission of the neurotransmitter from the 1st neuron. To inhibit the neuron transmission, a third neuroin acting on the first will cause GABA to close membrane pores. This will allow less Ca2+ to enter the membrane from outside the 1st cell, thus reducing the amount of neurotransmitter passed to the 2nd (object) cell. Thsi action of reducing the amount of nerotransmitter passed to the object cell (#2) is called presynaptic inhibition. A third cell can cause pre-synaptic facilitation, an increase of neurotransmitter passed from cell 1 to cell the object cell (#2) by opening the pores through which the Ca 2+ can pass accross the cell membrane in cell 1. There is an increae of nerotransmitter pessed to the object cell. Simply put withoput Ca2+ our nerves would not work, and our bones would become like noodles.
What is the eye connected to?
The eye is connected to the brain by the optic nerve. This nerve transmits visual information from the eye to the brain, allowing us to perceive the world around us.
What is biochemisty?
The chemistry of living things and their processes, such as the chemical processes that transfer nerve impulses, that give us sight, and aid in metabolism, like the Krebs cycle.
What is the largest sensory nerve of the eye and how does it contribute to vision?
The largest sensory nerve of the eye is the optic nerve. It carries visual information from the retina to the brain, allowing us to see and interpret the world around us.
Can you give us a project on electrolysis?
Can you separate H2O by making a electrolytic cell. im so smart right!
How do you make a 7th grade science project?
well first you need to know what it's about if your teacher didn't tell you exactly what it has to be about,then just say it is about cells in your body. the red blood cell,white blood cell,nerve cell,egg cell (this is only in female bodies(girls)),sperm cell (this is only in male bodies(boys)),nueron cell and the muscle cell now pick as many of these as you want ok. ok now you have chosen the cells tell us what the cell does then tell us about the parts of the cell and how it works label the parts of the cell using a diagram tell us what each part of the cell does. well that's it really from your dark orbit fan:poopyloopy dark orbit.
What is the nerve at the back of the eye?
The nerve at the back of the eye is the optic nerve. It transmits visual information from the retina to the brain, allowing us to see. Damage to the optic nerve can result in vision problems or even blindness.
What are the cells found in the human body?
In the human body we have lots of cells. Red blood cell's-this has a dip on it to carry oxygen around the body. The cell is blood White blood cell's-helps us when were sick. It fights the germs. Nerve cell's-is long and thin and it looks like an electric shock. It carries out reactions Sperm cell's-are found in male and helps make reproduction egg cell-found in a female and helps to make reproduction
What are the cell phones of the future going to be like?
Cell phones are changing constantly. The latest in cell phones is the smartphone, such as the iPhone. In the future, phones will continue to give us more access to data and be smaller and smaller.
