Homeostasis and temperature control Flashcards
1
Q
Contents of epidermis
A
- cornified layer
- granular layer
- malphigian layer
- hair shaft
- sweat pore
2
Q
Contents of dermis
A
- sweat duct
- sweat gland
- erector muscle
- receptor
- sebaceous gland
- hair papilla
- hair follicle
3
Q
Contents of hypodermis
A
- adipose tissue
- blood vessels
4
Q
Response of rise in temp
A
- vasodilation
- shunt vessels constrict
- sweat glands activated
- erector muscle relax
- less production of heat by liver
5
Q
Response of drop in body temp
A
- vasocontriction
- shunt vessels dilate
- sweat glands are inactive
- erector muscle contract
- liver produce more heat
- fat tissue ; minimise heat loss ; heat production
- shivering ; uncontrolled contraction of skeletal muscles to produce heat
6
Q
Response of rise in BGL
A
- starvation
- detected by receptors in pancreas
- pancreas secrete glucagon ; decrease insulin
- glucagon -> glucose
- decrease in respiration rate
7
Q
Response of drop in BGL
A
- detected by cells in pancreas
- pancreas secretes insulin ; decrease glucagon
- increase respiration
- glucose -> glycogen ( storage )
- increase in permeability of glucose in liver & muscle cells
