Intro into anatomy and histology Flashcards
system
Association of organs with a common function
organ
structures composed of 2 or more tissues
tissue
group of similar cells together with their intercellular matrix and perform a specific function
Epithelial tissue function
covers body surfaces; lines body cavities, forms glands
connective tissue function
protects and supports the body and its organs, binds organs together, stores energy reserves
muscle tissue function
Movement, cells are capable of contracting
nervous tissue function
initiates and transmits nerve impulses
connective tissue is made up of what fibres?
collagen
elastin
reticular
connective tissue consists of?
cells in an intercellular matrix which contains fibres and ground substance
collagen fibres
high tensile strength, little stretch
elsatin fibres
elastic, stretches without breaking
reticular fibres
thin collagen fibres, net-like
ground substance is?
Gelatinous proteoglycan -protein/sugar
Sponge-like, absorbs water
Resists compressive forces
loose connective tissue
lots of matrix, few fibres
adipose tissue: fat
eg. areolar tissue (beneath epithelium)
dense connective tissue
lots of fibres, little matrix
eg. cartilage, bone, ligament, fascia
