Study Notes
Glandular Types and Secretion Mechanisms
- Compound glands possess multiple ducts, each containing several sac-like secretory portions.
- Merocrine secretion involves the release of products via exocytosis without cell damage.
- Holocrine secretion entails the shedding of entire cells, releasing their contents.
Connective Tissue Characterization
- Dense connective tissue primarily consists of collagen fibers with some elastic fibers.
- Fibroblasts are the cells responsible for forming fibrous connective tissue.
- Osteoblasts play a crucial role in bone formation by producing the bone matrix.
Immune Response and Chemical Release
- Mast cells in connective tissue release chemicals that promote inflammation and initiate immune responses.
- Exocrine glands transport secretions through ducts to epithelial surfaces, maintaining direct contact with the external environment.
Connective Tissue Cell Functions
- Collagen fiber production is primarily carried out by fibroblasts within connective tissue.
- Adipocytes are primarily located in adipose tissue throughout the body, particularly in subcutaneous areas.
- Elastic fibers can be stretched or compressed and return to their original shape, providing flexibility.
Locations and Functions of Connective Tissue
- Dense irregular connective tissue is located in areas such as the dermis of the skin, providing structural support.
- Areolar connective tissue features relatively few protein fibers, abundant ground substance, and supports organs and tissues.
- Reticular connective tissue's primary function is to form a supportive framework for organs, particularly in lymphoid tissues.
Structures of Elastic Connective Tissue
- Dense regular elastic connective tissue is predominantly found in structures requiring elasticity, such as the walls of large arteries and certain ligaments.
