BSC 1005 Lecture Notes - Lecture 6: Sarcomere, Cardiac Muscle, Intracellular Parasite
Document Summary
Motor units the functional units of the neuromusular system twitch the active force response to a single stimulus tetanus the active force response to multiple stimuli at stimulation frequencies high enough that the muscle cannot fully relax between stimuli. The actin myosin cross-bridge cycle _____________ is the molecular explanation for how muscles contract. When present, occur because thick and thin filaments are highly organized. Are observed in skeletal & cardiac muscle when viewed with a microscope. Virus an obligatory intracellular parasite that carries a nucleic acid genome enclosed by a protein coat. Enveloped viruses viruses that have additional lipid membrane surrounding the protein coat. Virions also called virus particles; refers to a physical particle, whereas a virus is a more general term. Resolution of a microscope ability to distinguish two objects as separate entities. Bacteria and eukaryotic cells are in this size range. 0. 2 micron sized pores (will not remove viruses)
