-
Loose connective tissue proper, adipose
-
the ducts of endocrine glands
endocrine glands lose their ducts; hormone is secreted directly into blood or lymphatic vessel
-
the ducts of exocrine glands
exocrine glands retain their ducts; secretions are emptied through ducts to epithelial surfaces
-
lining of the esophagus
stratified squamous
-
lining of the stomach
simple columnar
-
alveolar sacs of lungs
simple squamous
-
tubules of the kidney
simple cuboidal
-
epidermis of the skin
stratified squamous
-
lining of bladder; peculiar cells that have the ability to slide over each other
transitional
-
forms the thin serous membranes; a single layer of flattened cells
simple squamous
-
single layer of cells of differing heights; may contain goblet cells and bear cilia
pseudostratified columnar
-
three characteristics of connective tissues
- Most have rich supply of blood vessels
- Are composed of many types of cells
- Matrix between cells
-
Noncellular, nonliving material in between cells of connective tissue
Matrix
-
Functions of connective tissues
- Protect
- Support
- Bind together
-
Two components of connective tissue matrix
-
3 primary germ layers
- endoderm (inner)
- mesoderm (middle)
- ectoderm (outer)
-
tissue cut along longest direction of the organ
longitudinal section
-
tissue cut perpendicular to length of organ
cross section
-
tissue cut at angle between cross and longitudinal section
oblique section
-
characteristics of epithelial tissue
- Layers of closely adhering cells
- Flat sheet with upper surface exposed to environment or an internal body cavity
- No blood vessels
- Rests on basement membrane
-
attaches bones to bones and muscles to bone
Dense connective tissue proper, regular
-
Acts as a storage depot for fat
Adipose connective tissue
-
the dermis of the skin
areolar connective tissue
-
Loose connective tissues, proper
-
Dense connective tissues, proper
-
Types of cartilage
- Hyaline
- Elastic
- Fibrocartilage
-
Make up the intervertebral discs
Fibrocartilage
-
Forms the hip bone
Osseous tissue
-
Composes basement membranes; a soft packaging tissue with a jellylike matrix
Areolar connective tissue
-
Forms the larynx, the costal cartilages of the ribs, and the embryonic skeleton
Hyaline cartilage
-
Provides a flexible framework for the external ear
Elastic cartilage
-
Firm, structurally amorphous matrix heavily invaded with fibers; appears glassy and smooth
Hyaline cartilage
-
Matrix hard owing to calcium salts; provides levers for muscle to act on
Osseous tissue
-
Insulates against heat loss
Adipose connective tissue
-
What 2 physiological characteristics are highly developed in neurons?
- Receive stimuli
- Conduct impulses
-
Special supporting cells that protect, support, and insulate the more delicate neurons
Neuroglia
-
Involuntarily controlled muscle
Cardiac & smooth
-
Striated muscle
Skeletal & cardiac
-
Muscle cells that have single nucleus
Cardiac & smooth
-
Muscle cells found in walls of stomach, uterus, and arteries
Smooth
