practical exam Flashcards
what is the top of layer in the skin
epidermis
identify the type of epithelium in this layer of the skin
stratified keratinised squamous epithelium
state the main functions of the epithelium
protection, water-proofing
what is the second layer in the skin
dermis
identify the type of epithelium of the dermis
dense irregular and areolar connective tissue
what is the last layer in the skin
hypodermis
identify the type of epithelium of the epidermis
areolar and adipose connective tissue
What are the layers of the epidermis ( deep to superficial)
- stratum basale
- stratum spinosum
- stratum granulosm
- stratum lucidum
- stratum corneum
what does the stratum basale contain
stem cells ( keratinocytes), melanocytes and tactile cells
What does the stratum spinosum contain
layers of keratinocytes, which contain immune cells
What does the stratum granulosum contain
3-5 layers where keratinisation begins
What does the stratum lucidium contain
thin, transparent layer
What does the stratum corneum contain
20-30 layers of dead, keratinised cells
Which layers are contained within the dermis
papillary and rectular layer
What does the papillary layer contain
areolar connective tissue, dermal papillae
What is the function associated with the papillary layer
increase surface area for nutrient exchange with the epidermis
What does the reticular layer contain
dense irregular connective tissue with collagen and elastin
What is the function associated with the reticular layer
strength and flexibility
Name the epithelium of the glomerulus
simple squamous cells
What are the cells on the outside of the glomerular capsule
podocytes
What is the function of the glomerulus
filter incoming blood to form filtrate
What are the three layers of veins and arteries
- tunica intima
- tunica media
- tunica adventina
what are the three layers of the heart
- epicardium
- myocardium
- endocardium
What is the function of the pericardium
resists excessive expansion
