| | GO:0090399 | | replicative senescence | | A cell aging process associated with the dismantling of a cell as a response to telomere shortening and/or cellular aging. |
| | GO:0019233 | | sensory perception of pain | | The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal. Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. This is a neurological process. |
| cellular component |
|---|
| | GO:0030424 | | axon | | The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. |
| | GO:0005903 | | brush border | | The dense covering of microvilli on the apical surface of a epithelial cells in tissues such as the intestine, kidney, and choroid plexus; the microvilli aid absorption by increasing the surface area of the cell. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0030425 | | dendrite | | A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
| | GO:0070062 | | extracellular exosome | | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm. |

| | GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |

| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0044306 | | neuron projection terminus | | The specialized, terminal region of a neuron projection such as an axon or a dendrite. |
| | GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| | GO:0045202 | | synapse | | The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
| | GO:0008021 | | synaptic vesicle | | A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane. |
