Name Date Laboratory Worksheet 6 Classification of Tissues Objective 1: Define the following terms: a) tissue; b) histology; c) basement membrane; d) matrix; e) ground substance; f) intercalated discs; g) axon ; h) dendrite ; i) cell body/soma (of a neuron) a. tissue f. intercalated discs b. histology g. axon c. basement membrane h. dendrite d. matrix i. cell body/soma (of neuron) e. ground substance Objective 2 : Indicate the general function, location and distinguishing anatomical/structural features for each of the four tissue types listed. Epithelium – all functions Epithelium Common Location Epithelium Distinguishing Anatomical/Structural Features Connective – all functions Connective Common Location (indicate at least five locations) Connective Distinguishing Anatomical/Structural Features Vayda Garcia 02/08/2021 is composed of grouping cells that make structural up organs and various body parts . Types formations found between of tissue include muscle , epithelial , cotlnneotire , myocardial cells of the heart . and nervous tissue . transmit signals between cells , is the study of microscopic structure also called nerve fibre , of tissues , is used to diagnose diseases in it is a portion of a nerve cell that carries nerve impulses humans , animals , and Plants . throughout the body . thin , pliable sheet - like type branched projections of extra cellular matrix . provides all and of a neuron that act to propagate + issue support , platform for complex electrochemical stimulation s from signalling other neural cells to cell body . intercellular substance of a tissue , - cell develops as hair or nails . Is found in body contains the nucleus and other supportive structures , which various connective tissues . support chemical processing of neuron . is transparent , colourless , and fills the spaces between fibres and cells . present in the composition of connective tissues . Secretion , selective absorption , protection , lines both the skin touts ide ) and trans cellular transport , the inside cavities and lumina covers body surface , cells and sensing NO blood of bodies .

All connective found around the body tissues have various nose , throat . Vascular levels of Vascularity . would be located in blood organs . Vessels and muscles .
Objective 2 Continued. Indicate the general function, location and distinguishing anatomical/structural features for each of the four tissue types listed. Muscle – all functions Muscle Common Location Muscle Distinguishing Anatomical/Structural Features Nervous – all functions Nervous Common Location Nervous Distinguishing Anatomical/Structural Features Objective 3: Provide the location (at least two) for each of the following types of epithelium: simple squamous, simple cuboidal, simple columnar, pseudostratified ciliated columnar, stratified squamous and transitional epithelium. Simple Squamous Pseudostratified Ciliated Columnar Simple Cuboidal Stratified Squamous Simple Columnar Transitional Epithelium Objective 4: List the different types of fibers and cells that may be found in the matrix of connective tissue. Fibers Cells (at least four types) 1. 1. 2. 2. 3. 3. 4. posture , circulation , smooth muscle located in respiration , Digestion , walls of hollow visceral organs urination , and childbirth . except the heart . skeletal excitability , contract ability , primary function is muscle is found attached to extensibility ( stretching ) , and the skeleton , are under elasticity ( back to normal after movement . voluntary control . Stretching ) Homeostasis , program Brain , spinal cord , spinal cord reflexes , and nerves ; C. N . S , C. N . S . is made up of the Brain memory and learning , and spinal cord , And the peripheral and voluntary control central Nervous system . nervous system is made of nerves that branch off from spinal cord and of movement extend to an parts of the body . Air sacs of the lungs , and the lining of the heart . lines the trachea and majority of the upper respiratory tract . In ducts and secretory portions of small glands and in lines esophagus , mouth , kidney tubules . and vagina . Bronchi , uterine tubes , uterus , and digestive lines bladder , urethra , and ureters . tract bladder . Collagen fibers fibroblasts Elastic fibers Adipocytes Reticular fibers macrophages lymphocytes
