unit 3 exocrine glandular epithelium

What is merocrine?

secrete their products through the plasma membrane by exocytosis

What is apocrine?

secrete their product by pinching off the plasma membrane. the process involves loss of cytoplasm

What is merocrine?

secrete their products through the plasma membrane by exocytosis

What is apocrine?

secrete their product by pinching off the plasma membrane. the process involves loss of cytoplasm

what is holocrine?

secrete their products by building up the product inside until the cell bursts.

what is an example merocrine?

salivary glands

what is an example of apocrine?

mammary glands

what is an example of holocrine?

sebaceous glands

What is adipocytes?

cells of fat tissue

What is osteocytes

cells of bones

what is chondrocytes?

cells of cartilage

What is fibrocytes?

cells of connective tissue

What is collagen

resist tension

What is elastin?

provides flexibility to tissue (can stretch)

what is reticulin

provide greater degree of movement than collagen; supports tissue structure and flexibility
