Anatomy Lab Quiz 2 Flashcards
Basic tissue types
Epithelial tissue, Muscle tissue, Connective tissue, Nervous tissue
Epithelial tissue functions
Coverings, linings, and glands
How to name epithelial tissue
cell shape and cell layers
-When labeling do layer then shape
ex: simple squamous
Squamous
Flat (nuclei)
Cuboidal
Square (round nuclei) e.g. balloon
Columnar
Column (oval nuclei) e.g. football shaped
Simple
1 cell layer
Stratified
2 or more cell layers
Pseudostratified
falsely stratified (lining of airways)
Transitional
changes from simple to stratified back and forth (because the lining stretches)
-only happens in urinary bladder and tubes that carry urine
Exocrine glands
produce secretion (have duct)
Endocrine gland
produce hormones (no duct)
Merocrine
thin, water, no cell destruction
e.g. sweat and salivary glands
Apocrine
thicker secreation, cell pinches off along with secretion
e.g. sweat glands of axilla, pubic area, areolar areas, and mammary glands
Holocrine
cell lost with thick secretion
e.g. oil glands
Mucous membrane
line open body cavities (epithelial)
Serous membranes
line closed body cavities (epithelial)
Synovial membranes
line joint cavities (connective)
Functions of connective tissues
connect
support
insulate
transport
protect
storage
body contours
organ framework
Embryonic connective tissue
Mesenchyme(stem cells)- differentiated into other adult connective tissues
Connective tissue proper (types)
Loose (areolar)
Dense regular
Dense irregular
Elastic
Reticular
Adipose
Loose (areolar)
primary area of water storage (edema)
Dense regular
tendons and ligaments
Dense irregular
dermis of skin
Elastic
blood vessel walls/ respiratory passageways
Reticular
organ framework
Adipose
long term energy storage
body contour
insulation
padding and protection
Cartilage
-hyaline
-embryotic skeleton
-articular cartilages
-nose
-respiratory tubes
-rib cartilages
Fibrocartilage
-intervetebral discs
-pubic arch
-menisci of knee
Elastic cartilage
-outer ear
-larnyx
-auditory canal
Bone tissue (osseous tissue)
compact, dense, or lamellar bone, spongy or cancellous bone
Vascular connective tissue
the liquid tissue
Muscle tissue types
smooth, cardiac, skeletal
Smooth muscle
organs and vessel walls, reproductive organs, and urinary tract
Smooth muscle characteristics
-lack striations
-spindle shaped
-involuntary (irritation and stretching, hormones and ANS)
-Slow to respond and slow to fatigue
Cardiac muscle characteristics
Only found in the heart
-striated
-intercalated discs (attachment and communication)
-intrinsic contractions
-fast to respond and slow to fatigue
Skeletal muscle
movement of skeleton, breathing, swallowing, control of bladder and rectum
Skeletal muscle characteristics
striated
voluntary- nerve stimulation usually fast to respond and fast to fatigue
Neurons
cell body
axon- away from cell body
dendrites- toward cell body
Reception-
conduction-stimulation
Neuroglia
supportive cells of the nervous system
