Modes of Secretion Merocrine – products are secreted by exocytosis (e.g., pancreas, sweat, and salivary glands) Holocrine – products are secreted by the rupture of gland cells (e.g., sebaceous glands)

Modes of Secretion Figure 4.5

Connective Tissue Found throughout the body; most abundant and widely distributed in primary tissues Connective tissue proper Cartilage Bone Blood

Connective Tissue Figure 4.6

Functions of Connective Tissue Binding and support Protection Insulation Transportation

Characteristics of Connective Tissue Connective tissues have: Mesenchyme as their common tissue of origin Varying degrees of vascularity Nonliving extracellular matrix, consisting of ground substance and fibers

Structural Elements of Connective Tissue Ground substance – unstructured material that fills the space between cells Fibers – collagen, elastic, or reticular Cells – fibroblasts, chondroblasts, osteoblasts, and hematopoietic stem cells

Ground Substance Interstitial (tissue) fluid Adhesion proteins – fibronectin and laminin Proteoglycans – glycosaminoglycans (GAGs) Functions as a molecular sieve through which nutrients diffuse between blood capillaries and cells

Ground Substance: Proteoglycan Structure Figure 4.7

Fibers Collagen – tough; provides high tensile strength Elastic – long, thin fibers that allow for stretch Reticular – branched collagenous fibers that form delicate networks

Cells Fibroblasts – connective tissue proper Chondroblasts – cartilage Osteoblasts – bone Hematopoietic stem cells – blood White blood cells, plasma cells, macrophages, and mast cells

Areolar Connective Tissue: Model Figure 4.8

Connective Tissue: Embryonic Mesenchyme – embryonic connective tissue Gel-like ground substance with fibers and star-shaped mesenchymal cells Gives rise to all other connective tissues Found in the embryo

Connective Tissue Proper: Loose Areolar connective tissue Gel-like matrix with all three connective tissue fibers Fibroblasts, macrophages, mast cells, and some white blood cells Wraps and cushions organs Widely distributed throughout the body

Connective Tissue Proper: Loose Figure 4.9a

Connective Tissue Proper: Loose Adipose connective tissue Matrix similar to areolar connective tissue with closely packed adipocytes Reserves food stores, insulates against heat loss, and supports and protects Found under skin, around kidneys, within abdomen, and in breasts Local fat deposits serve nutrient needs of highly active organs

Connective Tissue Proper: Loose Figure 4.9b

Connective Tissue Proper: Loose Reticular connective tissue Loose ground substance with reticular fibers Reticular cells lie in a fiber network Forms a soft internal skeleton, or stroma, that supports other cell types Found in lymph nodes, bone marrow, and the spleen

Connective Tissue Proper: Loose Figure 4.9c

Connective Tissue Proper: Dense Regular Parallel collagen fibers with a few elastic fibers Major cell type is fibroblasts Attaches muscles to bone or to other muscles, and bone to bone Found in tendons, ligaments, and aponeuroses

Connective Tissue Proper: Dense Regular Figure 4.9d

Connective Tissue Proper: Dense Irregular Irregularly arranged collagen fibers with some elastic fibers Major cell type is fibroblasts Withstands tension in many directions providing structural strength Found in the dermis, submucosa of the digestive tract, and fibrous organ capsules
