Primary tissue types Flashcards
How is gene expression monitored?
transcription factors
What are the 4 different tissues found in the body?
epithelia
neural tissue
muscle
connective tissue
What are the four ways epithelial cells are bound to one another?
tight junctions
desmosomes
gap junctions
adherens junctions
What is the structure of a neuron?
cell body
dendrites
axon
What are neurons?
simple elongated secretory cells that communicate by releasing chemicals by secretion at the end of cell processes
What is the function of the axon end-bulb?
the site of chemical neurotransmitter release
What is myelination?
the production of myelin around an axon
What are glial cells?
the supporting cast to the neurons in the CNS and PNS
What are the four types of connective tissue?
fibrocollagenous tissue
cartilage
bone
adipose tissue
What is an example of loose fibrocollagenous tissue?
around epithelia/organs
What is an example of dense fibrocollagenous tissue?
tendons and ligaments
What is an example of reticular fibrocollagenous tissue?
liver
lymph nodes
What are the three types of cartilage and their function?
elastic, hyaline, fibrocartilage
- brings flexibility, smooth joint movement and strength
What are the two types of bone?
trabecular
compact
What are the two types of adipose tissue and their function?
white fat - energy storage, insulation and protection
brown fat - produces heat by uncoupling oxidation phosphorylation in mitochondria
