1. What substance is in the little spiny lines connecting skin epithelial cells?
2. What structure waves back and forth to move substances along the epithelial surface?
3. What kind of filaments do microvilli contain?
4. What type of gland secretes substances right into the blood?
Homework Answers
- Keratin is present in the little spiny lines connecting skin epithelial cells. The spiny line, known as stratum spinosum is composed of 8-10 layers of keratinocytes. Keratin is synthesised from keratinocytes.
- Cilia (microscopic hair) waves back and forth to move substances along the epithelial surface. It helps to move foreign particles out of our body.
- Microvilli contain actin (microfilaments) filaments. Actin serves as the structural core of microvilli.
- Endocrine glands secrete substances (hormones) right into the blood.
Example: pituitary gland, thyroid gland etc
