Q

What are the names of different types of movement (bones)?

A

1.Flexion- reduces the angle between two bones
2.Extension- increases the angle of two bones
3.Abduction- moves away from the body
4.Adduction- moves towards the body
5.Rotation- joint can twist on its own axis
6.Gliding- surfaces of the joint slide over one another
7. Protraction- movement of the limb forward from the body
8. Retraction-movement of the limb back towards the body

35
Q

What are the three types of exocrine glands in the dermis?

A
  1. Sweat- Sudoriferous glands (dogs and cats only active in foot pads)
  2. Waterproof and lubricate- sebaceous glands secrete sebum which waterproofs skin and lubricates hair
  3. Ear wax- ceruminous glands are found in external ear canal and secrete wax
