13.

1 point

the presence of a synovial cavity, articular cartilage, synovial membrane and ligaments are characteristic of which type of joint?

suture

hinge

synchondrosis

symphysis

14.

1 point

_______ are specialized nerve endings of the skin that respond to such sensations as temperature and touch

cutaneous receptors

hair follicles

sebaceous glands

arrector pili

15.

1 point

Spinocerebellar tracts

give rise to conscious perception

are found in the dorsal columns of the spinal cord

terminate in the spinal cord

carry proprioceptive inputs to cerebellum

16.

1 point

you can cut hair without feeling pain because

hair follicles develop from epidermal cells and the epidermis lacks a nerve supply

hair follicles have no source of nourishment and therefore cannot respond

there are no nerves in the hair follicles

the shaft of the hair consists of dead cells

17.
