CH 4 TISSUES Flashcards
Transitional
lines urinary bladder and changes shape with pressure
Pseudostratified Columnar
lines respiratory tract and contains goblet cells
Keratinized Stratified Squamous
lines external surfaces, example: epidermis
Simple Squamous
lines blood vessels
Simple Cubodial
lines kidney tubules and bronchioles
Simple Columnar
lines inner lining of several organs: stomach, intestines and uterus
Reticular
loose connective tissue located at lymph organs (ex: spleen)
Irregular
dense connective tissue with collagen arranged without a specific pattern & can withstand stretching from several directions
Areolar
loose connective tissue that is gel-like, contains fibroblasts and immune cells, protects and cushions organs
Elastic
dense connective tissue primarily for stretching and returns to resting length between stretches
Regular
dense connective tissue that is poorly vascularized and contains collagen bundles that run parallel to each other to provide strength for tendons
Adipose
loose connective tissue that is highly vascular (lots of blood vessels), contains fat cells and absorbs shock
Elastic Cartilage
cartilage with capacity to stretch and is found at the external ear & epiglottis
Fibrocartilage
cartilage with collagen and is very strong, can absorb shock, & is found at intervertebral discs
What are the three main classes of connective tissue
Connective Tissue Proper, Fluid Connective Tissue, Supporting Connective Tissue
TRUE or FALSE
Loose connective tissue can be areolar, adipose, and reticular
TRUE
Dense connective tissue can be ____, ____, and ___.
Dense Regular, Dense Irregular, Elastic
____ and ____ can be Fluid Connective Tissue
blood and lymph
What are the three types of Supporting connective tissue?
Cartilage, Bone and Blood
Cartilage Supporting Connective Tissue can be
Hyaline, Fibrocartilage, Elastic
what is the composition and function of Bone Supporting Connective Tissue?
Composition- well vascularized and innervated, grand substance= contains calcium salts
Function- support and protect soft tissue, fat storage, blood synthesis
what is the composition and function of blood supporting connective tissue?
Composition- ground substance= plasma
fibers= clotting proteins
cells= red and white blood cells
Function- transports nutrients and waste (red), immune and protective function (white)
What are the three membranes?
Cutaneous, Mucous, Serous
TRUE or FALSE
Cutaneous Membranes have simple squamous epithelium and areolar connective tissue
FALSE
Mucous Membrane
structure= epithelium varies (stratified squamous, simple columnar, or pseudostratified) and areolar loose connective tissue. location= lines cavities that are open to the external environment
Nervous tissue composition and function
Composition- highly cellular, made of neurons that conduct electrical impulses and supportive cells
Neuroglia- supporting cells
Function- regulation, transmission, homeostasis
TRUE or FALSE
Skeletal, Smooth, Cardiac are all types of muscle tissue
TRUE
Cardiac Muscle Tissue is located in the ____, circulates blood, and maintains blood (_____) pressure
located in the heart, circulates blood, and maintains blood (hydrostatic) pressure
The study of tissue is _____.
Histology
Where is simple squamous found?
Air sacs of lungs, heart, kidneys, blood vessels, lymphatic vessels
Where is cilitated pseudostratified found?
Respiratory tract and lines trachea
Where is transitional tissue found?
Bladder urethra and lines your urethus
Which epithelia forms the walls of the air sacs across which gas exchange occurs?
Simple squamous (quick exchange)
_____ cartilage is found as the template for the skeleton embryo
Hyaline
The 4 tissue types in the human body are…
Nervous, Muscle, Epithelial, and Connective
Which tissue type transports nutrients and waste, immunity, and protective function?
Connective blood tissue
TRUE or FALSE
Goblet cells are found only in pseudostratified cilitated columnar epithelial
FALSE
Define holocrine and merocrine
Holocrine- all accumulate and cell ruptures to release product (oil glands)
Merocrine- secretes product by exocytosis (pancreas, sweat, saliva)
Which tissue forms ligaments and tendons?
Dense connective regular
_____ connect muscle to muscle
Ligaments
______ muscle to bone
tendons
Which tissue is a loose C.T. containing reticular fibers and WBC’s functioning as the stroma of the spleen?
Loose connective reticular tissues
Which tissue supports and protects and stores calcium?
Bone
Which tissue is a shock observer and acts as insulation?
Adipose (when your 20 these are the fat cells you will stick with and can’t remove or get rid of)
Which tissue provide tensile strength?
Dense regular and/or fiber cartilage
TRUE or FALSE
Does epithelial always exhibit polarity
TRUE
The tissue that functions as the stroma of the lymph?
Reticular
____ Tissue is foundation inthe movement of food, urine and reproductive tract secretions
Smooth muscle
TRUE or FALSE
A smooth muscle cell has a central nucleus and lacks striations
TRUE
What is the epithelial membrane that lines closed central cavities of the body?
Serous
What is the epithelial membrane that lines body cavities open to the exterior membrane?
Mucous Membrane
Endocrine, exocrine… which ducted/ ductless?
Endocrine- ductless
Exocrine- ducted
Two types of multicellular glands?
Merocrine and Halocrine
