Unmyelinated axons in the PNS are still surrounded by Schwann cells, but they are not myelinated, meaning the Schwann cells do not wrap themselves in layers around unmyelinated cells. { "9.1A:_Structure_and_Function_of_the_Muscular_System" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.1B:_Slow-Twitch_and_Fast-Twitch_Muscle_Fibers" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.1C:_Sliding_Filament_Model_of_Contraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.1D:_ATP_and_Muscle_Contraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.1E:_Control_of_Muscle_Tension" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "9.10:_Muscles_of_the_Lower_Limb" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.1:_Introduction_to_the_Nervous_System" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.2:_Smooth_Muscle" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.3:_Control_of_Muscle_Tension" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.4:_Muscle_Metabolism" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.5:_Exercise_and_Skeletal_Muscle_Tissue" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.6:_Overview_of_the_Muscular_System" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.7:_Head_and_Neck_Muscles" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.8:_Trunk_Muscles" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.9:_Muscles_of_the_Upper_Limb" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, 9.1A: Structure and Function of the Muscular System, [ "article:topic", "license:ccbysa", "showtoc:no" ], https://med.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fmed.libretexts.org%2FBookshelves%2FAnatomy_and_Physiology%2FAnatomy_and_Physiology_(Boundless)%2F9%253A_Muscular_System%2F9.1%253A_Introduction_to_the_Nervous_System%2F9.1A%253A_Structure_and_Function_of_the_Muscular_System, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), 9.1B: Slow-Twitch and Fast-Twitch Muscle Fibers, Describe the three types of muscle tissue. Cardiac myocytes are shorter than skeletal equivalents and contain only one or two centrally located nuclei. The cytoplasmic regions between the sarcomere branches are filled with mitochondria and smooth endoplasmic reticulum (sER) called sarcoplasmic reticulum, which envelopes each myofibril. Describe the properties, and functions of skeletal muscle tissue. Want to create or adapt books like this? We will discuss skeletal muscle more in-depth later in this module. Analyze how the size of a motor unit contributes to the function of a muscle. Bind the myofibrils of adjacent cells together. Cardiac muscle fibers aremononucleate, with only one nucleus per fiber, and they can sometimes bebranched. For oligodendrocytes in the CNS, the rest of the cell is separate from the process that forms a myelin sheath around a given axon segment. Neurons are responsible for sending and receiving messages. Neuroglia provide support and nutrients for neurons. Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected by intercalated discs to work as a single functional syncytium. Intercalated discs connect cardiac myocytes to an electrochemical syncytium and are responsible for force transmissions during muscle contraction. Neuroglia provides support and nutrients for the neurons. In turn, the workload is increased and ischemia is possible, eventually resulting in cardiac failure and death. We will discuss those special modalities in unit 3. Types of Muscle Tissue and Fibers | Biology for Majors II - Lumen Learning You also have the option to opt-out of these cookies. Secondly, they allow cardiac muscle tissue to function as a functional syncytium. 3 What is the purpose of intercalated discs quizlet?
