surround the papilla. This forms the lower part, or base, of the hair
follicle.
●● This is where hair grows from cell division
Answer: Hair bulb

Answer: horny epidermal tissue
●● The internal sheath is the...
Answer: innermost layer of the follicle, closest to the hair.
●● Hair papilla
Answer: is a cone shaped elevation of connective tissue that contains the
capillaries and nerves located at the base of the follicle that fits into the

●● (Hair Papilla)Blood vessels bring nutrients to the base of the...
Answer: bulb, causing it to grow and form new hair. Sensory never
surround the base of the follicle.
