● Serous membranes
○ MOST body cavities lines with a serous membrane OR contain an sub-cavity
formed by a nervous membrane
○ Double layered membrane
■ Continuous membrane folded on itself
■ Fluid between the layers
■ Function: Lubrication
○ Cranial and vertebral cavities = Meninges**
○ Pericardial Cavity = Visceral and Parietal PERICARDIUM
○ Pleural Cavities = Visceral and Parietal PLEURA
○ Peritoneal cavity = Visceral and Parietal PERITONEUM
What is a tissue?
• A group of structurally and functionally related cells that come together to perform common
functions
• ‘Histology’ is the study of tissues
– Histo = tissue
– Ology= study of
● Tissue Types FOUR primary tissue types, distinguished by the kinds and number of cells
and the composition of the extracellular matrix (ECM)
1. Epithelial
– ‘lining tissue’
– Glands – No visible ECM
2. Connective
– Connects tissues to one another
– Lots of ECM – ‘Proper’ (loose and dense)
– ‘Specialised’ (cartilage, bone, blood)
3. Muscle
– Contractile properties
– Skeletal, smooth and cardiac
– Little ECM, arranged in lines
4. Nervous – Signal transmission (send and receive) – Unique ECM
Epithelium
Document Summary
Most body cavities lines with a serous membrane or contain an sub-cavity. Double layered membrane formed by a nervous membrane. Pericardial cavity = visceral and parietal pericardium. Pleural cavities = visceral and parietal pleura. What is a tissue: a group of structurally and functionally related cells that come together to perform common functions, histology" is the study of tissues. Tissue types four primary tissue types, distinguished by the kinds and number of cells and the composition of the extracellular matrix (ecm: epithelial. Glands no visible ecm: connective. Lots of ecm proper" (loose and dense) Nervous signal transmission (send and receive) unique ecm. Covering or lining tissue ( epi" = upon") Found on all external and internal body surfaces. Act as barriers between the external environment, or between organs and fluid filled cavities. Epithelia classified according to: number of layers. 1 = simple (extremely thin, not resistant to mechanical stresses, better suited for diffusion/transportation)
