background image PNP 2264 Week 2 Notes Organs -groups of tissues with related function Tissues -cells performing similar functions (main types: connective, epithelial, muscle, nervous) Extracellular matrix (EMC)  - Is a substance produced by the cells in a specific tissue and can contain 
protein fibers, salts, H2O and dissolved macromolecules. Located on the 
outside of the cells
Epithelia Tissue -physical protection- from dehydration, abrasion and physical, chemical and  biological agents -selective permeability- regulates the passage of molecules in or out of a  region of the body -secretion-  some epithelial cells produce secretions such as sweat or saliva -sensations- can detect light, taste, sound, smell and hearing # cell

Protein screening cells filled

Exocrine glands-
pancreas, sweat 
glands, and 
salivary glands; 
endocrine glands,
such as thyroid 
and gonads
Ciliary dyskinesia  -cilia don’t beat properly - can result in Kartagener’s syndrome-----mirror image ----cilia movement  orientates organs   Secretory Epithelia  -often form glands Endocrine glands – do not possess ducts and secrets directly into the  interstitial fluid or bloodstream Exocrine glands- possess ducts and their cells secrete their products into  their ducts-- drain from small ducts to larger ducts. Almost all exocrine glands are 
derived from epithelial tissue, (ex. sweat, stomach secretions)
background image Exocrine:  Merocrine Secretion -contents secreted via vesicular exocytosis (most common; sweat, saliva,  most hormones) Exocrine:  Apocrine Secretion   -cytoplasm and secretion are excreted (pinched off) (ex. breast milk)  Exocrine:  Holocrine Secretion  -entire cell lost with secretion (ex. sebaceous/sweat glands) -not everything can be packaged into vesicles  Anticancer drugs, intended to target rapidly dividing cells, will often attempt arrest cells during at 
various points during the cell cycle (mitosis). Which type of gland would most likely experience side 
effects from undergoing this treatment?
