Chapter 4 BIO Flashcards
Primary tissues?
Epithelial
Connective
Muscle
Nervous
Tissues
A group of cells that are similar in structure and oer
Four basic types of tissues are
Epithelial
Connective
Muscle
Nervous
Linings for protection, coordination, synthesis, absorption, elimination
Epithelial
Supportive or structure tissue
Connective
For movement
Highly specialized connective tissue
Muscle tissue
For control and coordination
Highly specialized epithelial tissue
Nervous tissue
Cells performing a related function
Tissues
Lining or covering of organs
Epithelial
Protein and tissue
Connective
Tissues are classified by
Number of cell layers
Cell shape for
Simple layer
One layer
Stratified layer
More than one layer
Pseudostratified epithelial
Single layer of cells of varying heights
Each cell touches the basement membrane
Shapes of cells
Squamous
Cuboidal
Columnar
Glandular epithelial tissue
Secretion
One or a group of cells
Exocrine gland
Endocrine gland
Exocrine gland
Ducts lead to body surfaces.
Sweat glands, salivary glands are synthesized and stored for release then decreased into the duct system
Endocrine glands
Are ductless
Hormones are synthesized/stored for release, then secreted into the tissue fluid and diffused into blood stream.
Thyroid/parathyroid glands
Unicellular glands
Exocrine
Single cell glands
Goblet cells
Sebaceous glands produce and are a
Sebum which is oil
Are an exocrine gland
Gland Secreted directly into blood stream
Endocrine
Pseudostratified ciliated columnar epithelial
Goblet cells
Goblet cells
Exocrine glands
Mucus
In your digestive tract(not stomach)/respiratory tract
Exocrine glands multicellular and
Simple glands
Compound glands
Merocrine glands
Holocrine glands
Simple glands
Exocrine multicellular
Have single duct
Compound glands
Exocrine multicellular
Have branched ducts
Merocrine glands
Exocytosis
Going from inside out through secretory vesicles
Holocrine gland
Forms secretory material and bursts
Gland looks hollow
Active when hallow
Connective tissue characteristics
1) Cells, Extracellular Matrix
2) Embryological origin
3) inverted and vascular
connective tissue examples
Bone
Cartilage
Blood
Connective tissue proper (matrix)
Cells in connective tissue
Fewer rarely touching surrounded by matrix
Cells in the body always have what around them
Supporting material
What does the matrix have in it
Proteins lipids and nutrients for the main cells to feed off of
Out of Bone Cartilage Connective tissue proper Blood Which one is different
Blood, because it’s cells floating around and doesn’t give support
Chondro
Cartilage
Osteo
Bone
Fibro
Connective
Why is blood in the category of connective tissue
Because it come from the embryological origin of the meisoderm
Three layers of tissue in embryologic origin
Exctoderm
Meisoderm
Endoderm
Exctoderm turns into
Brain
Nervous system
Spinal chord
Mesioderm turns into
Everything connective tissue
Endoderm turns into
Your hallow gut
Internal organs
Extra cellular matrix is made up of
Ground substance (gelatinous glycoproteins)
Structural fibers
(Proteins, collagen, elastin, reticulum)
Which connective tissue isn’t vascular
Cartilage
I capillary beds
