#13 Structural Elements of Connective How are the functions of connective tissue reflected in its
structure?
Living cells are soft and fragile. The large amount of non-living matrix provides the strength needed for the normal function of connective tissues.

#15 Why do adipose cells remind people of a ring with a single jewel?
Figure 4.9b
They contain a large fat-filled vacuole occupying most of the cell. The nucleus is pushed to the periphery giving a ‘signet ring’ appearance

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: 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

Irritability and conductivityIrritability and conductivity#17 In what way are neurons similar to other cells?
They contain a nucleus and the usual organelles
#17 In what way are neurons similar to other cells?
They contain a nucleus and the usual organelles
How are they different?
They are different as their cytoplasm is drawn out into long processes

Describe how the unique structure of a neuron relates to its function in the body
Neurons conduct impulses over relatively long distances in the body. This is facilitated by the long cytoplasmic extensions

Nervous Tissue
• Branched neurons with long cellular processes and support cells
• Transmits electrical signals from sensory receptors to effectors
• Found in the brain, spinal cord, and peripheral nerves
