網頁Senses provide information about the body and its environment. Humans have five special senses: olfaction (smell), gustation (taste), equilibrium (balance and body position), vision, and hearing. Additionally, we possess general senses, also called somatosensation, which respond to stimuli like temperature, pain, pressure, and vibration. 網頁Cell–cell recognition is a cell's ability to distinguish one type of neighboring cell from another. This phenomenon occurs when complementary molecules on opposing cell …

Cell Signaling - The Definitive Guide Biology Dictionary

網頁Neurons communicate through a combination of chemical neurotransmitters and electrical gradients, and electroencephalography, or EEG, detects those electrical gradients to provide insight into the activity of the brain. Realize, however, that any single neuron's electrical activity is far too miniscule to be detected by scalp EEG, and thus what ... 網頁Reception: A cell detects a signaling molecule from the outside of the cell. A signal is detected when the chemical signal (also known as a ligand) binds to a receptor protein on the surface of the cell or inside the cell. 2.

網頁Figure 13.1.1 – Receptor Classification by Cell Type: Receptor cell types can be classified on the basis of their structure. Sensory neurons can have either (a) free nerve endings or (b) encapsulated endings. Photoreceptors in the eyes, such as rod cells, are examples of (c) specialized receptor cells. 網頁Cellular response. The binding of chemical signals to their corresponding receptors induces events within the cell that ultimately change its behaviour. The nature of these intracellular events differs according to the type of receptor. Also, the same chemical signal can trigger different responses in different types of cell. 網頁2024年6月22日 · 1.

"網頁Gene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. The set of genes expressed in a cell determines the set of proteins and ... " - The cell detects it's own signals
