Anatomy &Physiology
Must Do – Answer the following question using an
electronic device.
#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
#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
Figure 4.9b
#14 Connective Tissue Proper: Areolar
6, Composes basement membranes, soft package tissues with a
jellylike matrix

Areolar Connective Tissue: Model

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

#14 Connective Tissue: Elastic Cartilage
8, Provides a flexible framework for the external ear
Figure 4.9g
Connective Tissue: Fibrocartilage Cartilage
4, Makes up intervertebral discs
Figure 4.9h
Connective Tissue: Bone (Osseous Tissue)
5. Forms your hip bone
10. Provides levers for muscles to act on
Figure 4.9i
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
Figure 4.9f
#15 Why do adipose cells remind people of a ring with a single
jewel?
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

Connective Tissue Proper: Dense
Irregular

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 starshaped 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 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

#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
Dendrites

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
