Anatomy &Physiology

#11 What are the three general characteristics of Connective Tissue Connective tissues have:

#1 Mesenchyme as their common tissue of origin

#2 Varying degrees of vascularity

#3 Nonliving extracellular matrix, consisting of ground substance and fibers

Must Do – Answer the following question using an electronic device.

#12 What Functions are performed by Connective Tissue?

• A. Binding and support• B. Protection• C. Insulation• D. Transportation

#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.

#14 Connective Tissue Proper: Loose, Adipose

2. Acts as a storage depot for fat

11. Insulates against heat loss

#14 Connective Tissue Proper: Areolar

4, Makes up intervertebral discs

Connective Tissue: Bone (Osseous Tissue)

5. Forms your hip bone 10. Provides levers for muscles to act on

Connective Tissue: Hyaline Cartilage

7. Forms the larynx, the cover of the ribs, & the embryonic skeleton

9. Firm amorphous matrix invaded with fibers, glassy and smooth

#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

#16 Nervous Tissue, What two physiological characteristics are highly developed in neurons?

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

#18

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

InterActive Physiology ®: Nervous System I: Anatomy Review

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
