Animal Tissue and Animal Tissue Slides (BY124 Exam 1)
Connective
binds other tissues together (bone to bone (tendon), and muscle (ligament)) - collagen (protein/not stretchy) - elastic (elastin protein/stretchy) - reticular (comprised of collagen and attach to collagen)
Epethial
lines and covers (separation, outer layer of skin)
Lymphocyte
mononuclear leukocyte that produces antibodies
Muscular
movement - cardiac muscle: branched fibers joined by intercalated discs (desmosomes) - skeletal muscle: voluntary movement (attaches to bones) - smooth muscle: contractions = slower but last longer (found in walls of alimentary, genital, urinary tracts, arteries, and veins)
Erythocyte
red blood cell
Platelet
small blood fragment that collects at sites of injury to begin the clotting process
Desmosomes
Button-like anchoring junctions that prevent cells from being pulled apart (characteristic of heart muscle)
Gap junctions
(communicating junctions) provide cytoplasmic channels between adjacent cells (neuron synapses)
Adipose (fat) connective tissue
- adipocyte - nucleus
stratisfied squamous epithelium
- basement membrane
Pseudostratisfied ciliated columnar epithelium
- basement membrane - nucleus
Simple columnar epithelium
- basement membrane - nucleus
Simple cuboidal epithelium
- basement membrane - nucleus
Hyaline cartilage
- collagen fibers (matrix) - chondrocyte - lacuna
Areolar (loose) connective tissue
- elastic fibers - collagen fibers
Elastic cartilage
- elastic fibers (matrix) - chondrocytes - lacuna
Human scalp (dermis contains dense irregular tissue)
- epidermis - dermis - dense irregular connective tissue - sweat gland - hair shaft - hair follicle - fat
Fibrous tissue (dense regular connective)
- fibroblast - collagen fibers
Bone
- lamellae - Haversian canal - canaliculi - lacuna
Sickle cell anemia
- misshapen RBC
Neuron
- neuron - nucleus - soma
Frog Blood
- nucleated RBC
Striated skeletal muscle
- nucleus - striations
Intercalated discs (cardiac muscle)
-intercalated disc
Small intestine
-smooth muscle (found in outer layer)
Tight junction
A type of intercellular junction in animal cells that prevents the leakage and transportation of substances between cells.
Neutrophil
A type of white blood cell that engulfs invading microbes and contributes to the nonspecific defenses of the body against disease.
Lymphocytic leukemia
Leukemia characterized by enlargement of lymphoid tissues and lymphocytic cells in the circulating blood
Monocyte
an agranulocytic leukocyte that performs phagocytosis to fight infection
Nervous
transmits impulses and responds to stimuli (nerves) - Neurons 1. soma (cell body): contains nucleus and most of cell organelles 2. dendrites: conducts stimuli in cell body 3. axon: conducts impulse away from cell body
Basophil
white blood cell containing granules that stain blue; associated with release of histamine and heparin
Eosinophil
white blood cell containing granules that stain red; associated with allergic reactions
Leukocytes
white blood cells
