Histology and Microscopy Flashcards
Types of Muscular Tissue
Skeletal
Cardiac
Smooth
Characteristics of Muscular Tissue
contracts with force
responsible for movement
involuntary contractions pump blood
cells called fibers
Skeletal muscle tissue structure
very long
multiciliate
striations
Skeletal Functions
moves the body
voluntary
Skeletal Location
attached to bone or other connective tissue
Cardiac Muscle Tissue Structure
cylindrical cells
single, centrally located nucleus
branched
Cardiac Function
pumps blood
involuntary
Cardiac Location
heart only
Smooth Muscle Tissue Structure
celled are tapered
no striations, single nucleus
no gaps
Smooth Function
regulates size of organs
forces fluid through tubes
involuntary
Smooth Location
hollow organs ( stomach and large intestines)
Nervous tissue structure
Neurons: dendrites, cell body, axon
Glial cells
Nervous Function
Transmit information in form of action potentials
Nervous LOCATION
brain
spinal cord
ganglia
Connective Tissue
Function: connecting tissues to one another
supporting and moving parts of the body
protecting
transporting
storage
Classification:
loose
dense
cartilage
blood
bone
Loose Connective (areolar)Structure
cells within fine network of fibers and blood vessels
(fibroblast, macrophages, lymphocytes)
Loose Function
loose packing
support
nourishment for associated structure
Loose Location
distributed widely
basement membrane
packing between glands
muscles and nerves
attached to skin’s underlying tissues
Loose Adipose Structure
little ECM
adipocytes very full of lipids
cytoplasm and nucleus at periphery
