There are three major types of epithelium based on the number of cell layers in each:
Simple epithelium, Stratified epithelium, Pseudostratified columnar epithelium
Types of Multicellular exocrine glands according to structure
Simple glands, Compound glands, tubular, acinar or alveolar
three types of epithelium based on idealized shapes of the epithelial cells:
Squamous, Cuboidal, Columnar
What are the three thing that Cell Connections do?
These structures do three things: (1) mechanically bind the cells together, (2) help form a permeability barrier, and (3) provide a mechanism for intercellular communication. BBC
extracellular matrix of connective tissue has three major components
(1) protein fibers, (2) ground substance, and (3) fluid.
Cells of connective tissues
Adipocytes (fat), mast cells (plays a role in inflammation), white blood celss, macrophages (eats foreign and injured cells), Undifferentiated mesenchymal cell
proper loose connective tissue consists of
Areolar, Adipose tissue, Reticular tissue
neuron is composed of three major parts:
a cell body, dendrites, and an axon.
Chromosomes begin migrating towards the poles if the cell during the
anaphase
Two major categories of connective tissue
are embryonic and adult. Embryonic connective tissue is called mesenchyme.
what are the 4 types of glial cells found in the central nervous system
astrocytes, ependymal cell, microglia, oligodendrocyte
characteristics of connective tissues
bind other tissues and organs together, create new cells from tissues, involved in delivering the nutrients to tissue, separate tissues from each other.
What are the 2 types of fluid connective tissue
blood and hemopoietic tissue
what characteristic does the oligodendrocytes and schwann cells have in common
both provide myelination
which part of the neuron receives and process information
cell body
Three types of Extracellular Matrix protein fibers
collagen, reticular, and elastic
Adult connective tissue consists of three types:
connective tissue proper (loose and dense), supporting connective tissue (cartilage and bone), and fluid connective tissue (blood).
roles of connective tissue
cushioning, insulating
what is division of the cytoplasm called
cytokinesis
What are the 4 Cell connections
desmosomes, Hedmidesmosomes, tight junctions, gap junction
Dense regular elastic connective tissue
elastic tissue that forms vocal cords
four primary tissue types,
epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
parts of the body that coincide with ectoderm
epithelial, nervous tissues, outer portion of the skin, peripheral nerves
types of glands
excorine, endocrine
perimysium covers what
fascicle
granulation tissue consists of
fibroblasts, collagen, capillaries
Reticular
fibroblasts, fibrocytes and reticular fibers, provides internal framework for the liver, spleen and lymph nodes, found in bone marrow
Elastic cartilage
found in areas where ridged but elastic properties are needed, in ear, larynx
Dense irregular collagenous connective tissue
found in the deep layers of the skin and the white of the eye.
Dense irregular elastic connective tissue
found in the walls of the arteries.
tissue repair
fresh wound, clot forms, scab appears and epithellium grow into the wound, fibroblasts have formed granulation tissue, scab is sloughed off, granulation tissue is replaced by new connective tissue
Areolar
functions as packing material or mesh-work providing an internal framework or an external wrapping around organs or as layers, basement membrane of epithelia, found in tissues that hold muscles together, forms serous membrane in lungs
The two major components of the Ground Substance of the Matrix are
hyaluronic acid and proteoglycans.
where are chondricytes and osteocytes located
in the lacuna
where are chondrocytes and osteocytes located
in the lacuna
the time between cell division is called
interphase
DNA replication occurs in what phase?
interphase in S phase
Mitotic spindle fibers attach to chromosomes via special structures termed
kinetochores
parts of the body that coincide with endoderm
lining of the digestive tract
what are the changes in extracellular materials and tissues in older adults
loss of elasticity, loss of flexibility of connective tissues, collagen fibers
types of exocrine according to products.
merocrine, Apocrine, Holocrine
In which part of the cell cycle do the chromosomes align
metaphase
Fibrocartilage
more collagenous fibers than chondrocytes, found in areas where more stress is placed on cartilage, found in knee, jaw, and between the vertebrae.
Hyaline
most common, found in the rib cage and within the trachea and bronchi, apex of the nose, long bone joints, the cells that are in it are called chondrocytes
What are the three major categories of internal membranes
mucous, serous, and synovial membranes. Mucous Membranes
types of excorine glands according to cells
multicellular, unicellular glands
what are the Neurons structures
multipolar, bipolar, Pseudo-unipolar neurons
parts of the body that coincide with mesoderm
muscle, bone, connective, mesenchymal tissue, blood
nervous tissue is composed of 2 types of cells
neurons and glial cells
Dense regular collagenous connective tissue
parallel fibers, bind bone to muscle (tendons) or bone to bone (ligaments)
what are the 2 tissue repairing process called
primary union, secondary union
mitosis 4 sub-phases in the correct order
prophase, metaphase, anaphase, telophase (divison of the nucleolus)
What are the Inflammation five major manifestations:
redness, heat, swelling, pain, and disturbed function or hemorrhage
Proper Dense Connective Tissue can be subdivided into two major groups:
regular and irregular.
2 types of glial cells found in the peripheral nervous system
schwann and satellite cell
What are the three types of muscle tissue
skeletal, cardiac, and smooth muscle
which type of muscle tissue is found in the walls of hollow organs
smooth muscle
What are the 2 types of bone
spongy bone and compact bone
cktokinesis is complete at the end of which phase
telophase
cytokinesis
the division of the cytoplasm and organelles
three embryonic germ layers
the endoderm , the mesoderm, and the ectoderm
Adipose
unusual because highly cellular, comes from adipocytes (fat cells), stores energy, foun immediately deep to the skin
what are the proper dense irregular connective tissues?
Dense irregular elastic connective tissue , Dense irregular collagenous connective tissue
what are the proper dense regular connective tissues?
Dense regular collagenous connective tissue, Dense regular elastic connective tissue
interphase 3 sub-phases
G1 phase, S phase, G2 phase (cell grows and prepares to divide)
What are the three types of cartilage:
Hyaline, , Fibrocartilage, Elastic cartilage
what is the function of nervous tissue
Monitor internal and external environment, process information, initiate commands
Epithelial characteristics
Mostly composed of cells, Covers body surfaces, Distinct cell surfaces, Cell and matrix connections, Nonvascular, Capable of regeneration. DNR @ CSM
