Chapter 6 Flashcards
a group of similar cells that perform a common function
tissue
extracellular material that surrounds the cells
Matrix
the biology of tissues.
Histology
skin tissue, and linings of some systems.
Epithelial tissue
bone, cartilage, tendon, and ligament
Connective tissue
used for communication throughout the body
Nervous tissue
Tissue for movement
Muscle tissue
epithelial tissue attached to the underlying connective tissue using this basement membrane as an adhesive
Basement membranes
Simple epithelium tissue
Simple squamos
discharge into ducks, salivary gland.
Exocrine
specialized for secretory activity
Grandular epithelium
discharge directly into blood or interstitial fluid, pituitary, thyroid, adrenal.
Endocrine
collect product inside the cell and rupture for release, destroys the whole cell.
Holocrine gland
Collect product near the apex and secrete by pinching off, harms the cell
apocrine gland
direct discharge, doesn’t harm the cell.
Merocrine gland
the most diverse type of tissue and is found around nearly every organ
Connective tissue
Fat cells
Adipose
bundles of collagenous fibers that withstand multidirectional stretching.
Dense irregular
3d web of support, works as a framework
reticular
mostly collagen and can resist stretch
Collagenous dense regular
Osseous Tissue
Bone
Hard shell of the bone
Compact bone
Bone producing cells
Osteoblasts
bone destroying cells
Osteoclasts
spongy bone that supports red bone marrow
Cancellous Bone
cartilage cells produce the tough, gristle like ground substances.
Chondrocytes
without bloods cells and relies on diffusion
Avascular
Muscle that attaches to bone, it is striated
Skeletal Muscle
Heart muscle that is striated and has intercalated discs
Cardiac muscle
Muscle that is found on organ walls and has no striations
Smooth Muscle
nerve cell
Neuron
regulates and integrates the body.
Nervous Tissue
Supporting framework of cells
Neurologia
phagocytic cells repair damage and fill gaps.
Regeneration
4 types of tissue
Epithelial, connective, Muscle, nervous
Unusually thick scar
Keloid
3 types of Muscle Tissue
Cardiac, Smooth, Skeletal
5 functions of epithelial tissue
Protection, sensory, Secretion, Absorption, Excretion
2 types of epithelial tissue
Membranous, and Grandular
4 types of Connective tissue
fibrous, bone, cartilage, blood
3 Types of Cartilage
Hyaline, Fibro, Elastic
4 Functions of Connective tissue
Connect, Support, Transport, Defend
3 ECM Fibers
Collagenous, Reticular, Elastic
3 types of blood cells
red cells, white cells, and platelets
3 Types of Epithelial membrane
Cutaneous, Serous, Mucous
Simple squamos is found
in the lungs and lining of blood vessels
A membrane can be
a wall or a lining
Simple columnar make up mucus membrane of
stomach, uterus, respiratory tract.
Simple squamos has a
thin nature and is good at diffusion.
Simple cuboidal are
are good at secretion and make up glands
Different types of columnar
are goblet, cilia, and microvilli
Grandular Epithelium may function as a unicellular gland
or it may function in clusters, such as solid cords or follicles.
Collagenous fibers are made of collagen bundles and
are tough fibers that provide strength and resist stretch, they contribute to aging.
Connective tissue is mostly composed of
ECM
The matrix determines if the tissue is
gel-like, firm, hard, tough, or delicate.
Reticular fibers are
collagen networks that support capillaries and nerves.
Loose Ordinary Areolar tissue is loose because it is
stretchable, ordinary because it is common and widespread, and areolar because it has space in-between it.
Elastic fibers are made of stretchy
elastin and make up the ear, they are yellow.
Hyaline Cartilage is the most prevalent
cartilage and is at the end of bones.
Adipose is support and
protection for organs while being an insulator and storing calories.
Bone Tissue is made of
osteocytes/bone cells
Fibrous Cartilage is the toughest and most durable cartilage
it is rigid and full of collagen.
Collagen repairs
the connective tissue
Elastic Cartilage
is very flexible
Epithelial and connective tissues
are best at repairs
If deep damage occurs it will result in
a dense, fibrous repair.
Some neurons OUTSIDE the brain and spinal
cord can repair themselves only if neurologia are present.
Muscle does not
heal well
Fibrous connective tissue sometimes
heals the wound resulting in a loss of normal function.
Normally, brain and spinal tissue in adults
do not grow, leading to permanent damage
The only type of connective tissue membrane is
synovial
Cutaneous membrane covers the surfaces that are
exposed externally, they are 16% of body weight.
Serous membrane covers
cavities that are not externally exposed.
Pleura and peritoneum are both
membranes that are serous.
Pleura surrounds the
lungs and lines the thoracic cavity.
Peritoneum covers abdominal viscera
and lines the abdominal cavity.
They secrete lubricant
to avoid the lungs from chafing
Mucous membrane lines surfaces that are exposed to the outside
, they are the urinary, respiratory, digestive, and reproductive tracts. It produces mucous.
Synovial lines the spaces
between bones and joints
