| GO:0004993 | G protein-coupled serotonin receptor activity | molecular_function | Combining with the biogenic amine serotonin and transmitting the signal across the membrane by activating an associated G-protein. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates. [GOC:ai] |
| GO:0007193 | adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway | biological_process | A G protein-coupled receptor signaling pathway in which the signal is transmitted via the inhibition of adenylyl cyclase activity and a subsequent decrease in the intracellular concentration of cyclic AMP (cAMP). [GOC:dph, GOC:mah, GOC:signaling, GOC:tb, ISBN:0815316194] |
| GO:0014827 | intestine smooth muscle contraction | biological_process | A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. This process occurs in the intestine. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The intestine is the section of the alimentary canal from the stomach to the anal canal. It includes the large intestine and small intestine. [GOC:mtg_muscle, MA:0001539, MSH:D007422] |
| GO:0040012 | regulation of locomotion | biological_process | Any process that modulates the frequency, rate or extent of locomotion of a cell or organism. [GOC:ems] |
| GO:0042310 | vasoconstriction | biological_process | A decrease in the diameter of blood vessels, especially arteries, due to constriction of smooth muscle cells that line the vessels, and usually causing an increase in blood pressure. [GOC:pr, ISBN:0192800752] |
| GO:0050795 | regulation of behavior | biological_process | Any process that modulates the frequency, rate or extent of behavior, the internally coordinated responses (actions or inactions) of whole living organisms (individuals or groups) to internal or external stimuli. [GOC:go_curators, GOC:pr] |
| GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| GO:0045202 | synapse | cellular_component | The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton 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 terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. [GOC:aruk, ISBN:0198506732, PMID:24619342, PMID:29383328, PMID:31998110] |
| GO:0007198 | adenylate cyclase-inhibiting serotonin receptor signaling pathway | biological_process | An adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway initiated by serotonin binding to its receptor, and ending with the regulation of a downstream cellular process. [GOC:dph, GOC:mah, GOC:signaling, GOC:tb] |
| GO:0030594 | neurotransmitter receptor activity | molecular_function | Combining with a neurotransmitter and transmitting the signal to initiate a change in cell activity. [GOC:jl, GOC:signaling] |
| GO:0007268 | chemical synaptic transmission | biological_process | The vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse. [GOC:jl, MeSH:D009435] |
| GO:0030425 | dendrite | cellular_component | A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses 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:0007187 | G protein-coupled receptor signaling pathway, coupled to cyclic nucleotide second messenger | biological_process | A G protein-coupled receptor signaling pathway in which the signal is transmitted via the activation or inhibition of a nucleotide cyclase activity and a subsequent change in the concentration of a cyclic nucleotide.
