Explanation / Answer
1) Functions of cartilages include;
Muscle contraction- during inspiration and expiration ,costal cartilage helps in the movement of rib cage due to increased or deceeased volume of lungs.
Supporting soft tissues- as it is part of rib cage,also found in nose and ear.
As a model for the formation of most bones in body- calcification of cartilages results in formation of bones.
2) True regarding hair are;
The root projects beyond the skin - as it originates from hair follicle which us inserted into the hair root sheath.
Terminal hair is pigmented and comprises the eyebrows -they are different from vellus hair beind dark and thick.
They are found in face (as beard,eyebrows).
Pubic hairs are also of this type.
The other two is wrong.
Lanugo are the hair which covers the body of newborn or infant.
Single hair is termed as a strand.
3) answer is hyaline cartilage.
This is termed as costal cartilage,it helps in the movement of rib cage during inspiration and expiration.
4)
Fleshy external part of the ear - elastic cartilage
Trachea- hyaline cartilage
Pubic symphysis - fibrocartilage
5)answer is Vasocontrict.
This helps in reduced blood flow to the skin and more blood flow to the central body area and causes reduction in heat loss.
6) Integumemts are - hairs,skin,glands,nails and nerves.Their main fuction is protection of body.
True regarding integuments are;
Protection
Prevention of water loss (through hair in cold temperature and sweat glands present in skin)
Temperature regulation.( Through sweat glands)
Immune defence( through hairs in the nose and ears,through skin against microorganisms etc.)
7) the correct function is sweat glands.
It helps in temperature regulation.
8) The shaft of long bone is called diaphysis while the expanded , knobby region at each end is called epiphysis.
