Question

an exocrine gland that loses small parts of its cell bodies during secretion, as is the case for the mammary gland, is further classified as a(n) __________ gland. apocrine endocrine merocrine holocrine question 19 2 pts what is the functional classification of the sagittal suture? diarthrosis fibrous synchondrosis synarthrosis

Explanation:

• For the first question:
• Apocrine glands are a type of exocrine gland. In apocrine secretion, small parts of the cell bodies (apex of the cells) are lost during secretion. The mammary gland is an example of an apocrine gland.
• Endocrine glands secrete hormones directly into the bloodstream (no ducts), which is not the case here as we are talking about an exocrine gland (has ducts).
• Merocrine (eccrine) glands secrete substances by exocytosis without losing cell parts.
• Holocrine glands release their secretions by the rupture of the entire cell (cell dies), which is different from the description of losing small cell - body parts.
• For the second question:
• Diarthrosis is a freely movable joint (e.g., most synovial joints), and the sagittal suture is not a diarthrosis.
• Fibrous is a structural classification of joints (based on the tissue that binds them), not a functional classification.
• Synchondrosis is a cartilaginous joint (structural classification).
• Synarthrosis is a functionally immovable joint. The sagittal suture, which joins the two parietal bones of the skull, is a synarthrosis as it allows very little to no movement.

Answer:

• First question: Apocrine
• Second question: Synarthrosis
