  • Interesting fact: The main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol). The membranes of certain nerve cells in the brain contain protein receptors that bind to THC. Once securely in place, THC kicks off a series of cellular reactions that ultimately lead to the high that users experience when they smoke marijuana
    • n membrane A thin pliable expansive structure of the body; an expansion of any soft tissue or part in the form of a sheet or layer, investing or lining some other structure or connecting two or more structures. The term is used in the widest sense, with little or no reference to the kind of tissue which may be concerned, the membranous quality depending upon thinness and pliability, not upon texture or fabric. No hard parts, as bone and cartilage, come within the definition of membrane. Most membranes are fibrous—that is, consist wholly or in part of some form of connective tissue, in or on which may be other and more special form-elements, as the layers of cells peculiar to the mucous, the serous, and other special membranes. In some cases a sheet of nerve-tissue, or of muscle-tissue, constitutes a membrane, with little admixture of other elements. Some membranes chiefly consist of a network of blood-vessels, with little connective tissue. Most membranes are specified by qualifying terms. See phrases following.
    • n membrane In entomology, specifically, the membranous terminal part of a hemielytrum; the membrane of the fore wing of a hemipter. See cut under clavus.
