Musculoskeletal System and Tissues Quiz

Squamous epithelium = Flattened and thin cells Cuboidal epithelium = Boxy, as wide as it is tall Columnar epithelium = Rectangular, taller than it is wide Pseudostratified epithelium = Single layer of irregularly shaped cells that give the appearance of more than one layer

Tight junctions = Restrict movement of fluids between adjacent cells Gap junctions = Allow direct communication and passage of ions and small molecules between cells Anchoring junctions = Provide strong yet flexible connection between epithelial cells Adherens junctions = Help epithelial layers resist separation during various contractile activities

Cilia = Allow movement of fluids and particles along the cell surface Basal lamina = Forms a basement membrane to anchor layers together Glycoproteins and collagen secretion = Forms basal lamina by interacting with the reticular lamina from connective tissue Mucous secretion = Traps incoming microorganisms and particles

<p>Shape of cells can vary = Depending on the degree of stretch within a tissue Number of layers can vary = Depending on the degree of stretch within a tissue Appearance of cells can vary = Depending on the degree of stretch within a tissue Degree of stretch-dependent variation = Variation in shape, number of layers, and appearance depending on tissue stretch</p> Signup and view all the answers

<p>First line of protection from physical, chemical, and biological damage = Control permeability by allowing selective transfer of materials across its surface = Capable of rapidly replacing damaged and dead cells = Capable of secreting mucous and specific chemical compounds onto their apical surfaces =</p> Signup and view all the answers

<p>Epithelial tissue = Cells that cover external surfaces of the body Connective tissues = Support and connect different types of tissues in the body Muscular tissues = Responsible for movement and locomotion Nervous tissue = Responsible for transmitting electrical signals and coordinating bodily functions</p> Signup and view all the answers

<p>Highly cellular, with little or no extracellular material present between cells = Adjoining cells form specialized intercellular connections called cell junctions Specialized intercellular connections called cell junctions = Highly cellular, with little or no extracellular material present between cells Cells that cover external surfaces of the body = Responsible for various functions and glandular activities Derived from all three major embryonic layers = Originates from ectoderm, endoderm, and mesoderm</p> Signup and view all the answers

<p>Cutaneous membranes = Develops from ectoderm Mucous membranes = Majority originate in the endoderm Endothelium = Lines vessels in lymphatic and cardiovascular systems Mesothelium = Lining the true cavities</p> Signup and view all the answers

<p>Red muscle fibers = Rich in myoglobin and suitable for endurance activities White muscle fibers = Less myoglobin and suitable for quick, powerful contractions Smooth muscle fibers = Found in the walls of internal organs and blood vessels Striated muscle fibers = Voluntary muscles attached to bones for movement</p> Signup and view all the answers
