Week 10 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 Figure 4.9b 2. Acts as a storage depot for fat 11. Insulates against heat loss

#14 Connective Tissue Proper: Areolar Figure 4.9a 6, Composes basement membranes, soft package tissues with a jellylike matrix

Areolar Connective Tissue: Model Figure 4.8

#14 Dense Connective Tissue Proper: Regular Figure 4.9d 1; Attaches muscles to bones or bones to bone 3; The dermis of the skin

#14 Connective Tissue: Elastic Cartilage Figure 4.9g 8, Provides a flexible framework for the external ear

Connective Tissue: Fibrocartilage Cartilage Figure 4.9h 4, Makes up intervertebral discs

Connective Tissue: Bone (Osseous Tissue) Figure 4.9i 5. Forms your hip bone 10. Provides levers for muscles to act on

Connective Tissue: Hyaline Cartilage Figure 4.9f 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: Blood Figure 4.9j

Connective Tissue Proper: Dense Irregular Figure 4.9e

Connective Tissue Proper: Loose Figure 4.9c

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? Figure 4.10 Irritability and conductivity #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

Axon Dendrites #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 Sketch and Label the next 13 slides as they correspond to your packet
