Mucous
thin epithialial cells and connective tissue
mucous lubricant
lines communicative passageways
moist to reduce friction and facilitate secretion/absorption
serous
internal subdivision of ventral cavities thin transparent parietal (inner) and visceral (outer) layers transudate fluid between minimise friction lines pleural cavity
synovial membrance
layer of fibroblasts and macrophage control the composition of synovial fluid
lubricates articular cartilage
movement of joint stimulates the formation and circulation if synovial fluid
cutaneous
layers of squamous epithelium
dermis-underlying conncetive tissue
epidermis- superficial epithelium
skin- dermis
Elastic and collagen fibres – tolerant to twisting and stretching. Lymphatic vessels, blood vessels, nerves and glands
function of skin
protection production secretions synthesis detection (sensory) excretion storage maintenance
