Advanced Bio mod 3 study guide Q's
1. A. The outer portion of skin, formed by epithelial tissue which rests on the dermis
B. Dense irregular tissue that forms the deep layer of the skin
C. Loose connective tissue underneath the dermis which connects the dermis to muscle or bone
D. The process of manufacturing blood cells
E. Dense bone matrix enclosing only a few small spaces
F. Bone with many small spaces or cavities surrounding the bone matrix
G. Bone formation
H. Hyaline cartilage that covers the ends of a bone in a joint
I. The portion of the skeleton that supports and protects the head, neck and trunk
J. The portion of the skeleton that attaches to the axial skeleton and has the limbs attached to it
K. A junction between flat bones of the skull
L. A projection on a bone
M. A passageway
N. A hole
O. A hollowed out space in a bone
2. The epidermis and Dermis. The epidermis has keratinized cells, and the dermis has the papillae
3. They allow for maximum blood flow to the basement membrane, and from there the blood diffuses into the cells above
4. If a cut runs along the lines of tension in the skin, then it will heal faster and with less scarring, but if it runs against them it will gape open and take longer to heal.
5. The hair follicles are made of epithelial tissue, so they can go through mitosis and replace the tissue above them
6. The hair follicles are made of epithelial tissue, so they can go through mitosis and replace the tissue above them
7. Sebaceous glands produce oil that softens the skin and gives some protection from bacteria
8. They produce sweat, which travels up the sweat ducts and comes out of your pores to help you cool off
9. Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum
10. The cells are alive in the stratum basale and stratum spinosum
11. They produce melanin
12. A. Nerves
B. Hairs
C. sweat pore
D. blood vessel loop
E. sebaceous gland
F. sweat duct
G. sweat gland
H. adipose tissue
I. arrector pili muscle
J. vein
K. artery
L. hair follicle
M. hypodermis
N. dermis
O. epidermis
13. The medulla, the cortex and the cuticle. The medulla is the central layer that has soft keratin, the cortex makes up most of the hair and has the hard keratin, and the cuticle is a single layer of hard keratin that overlaps like shingles on the outside of the hair and protects it
14. The hair matrix is a mass of undifferentiated cells that will eventually differentiate to become new hair cells
15. There are merocrine sweat glands
16. Sebaceous glands are holocrine glands
17. A. Flat bone
B. long bone
C. Short bone
D. sesamoid bone
E. irregular bone
18. It is found in the medullary cavity
19. It provides support, protection, movement, storage, and Hemopoiesis
20. A. Skull
B. Mandible

I. femur
J. patella
K. tibia
L. fibula
M. tarsals
N. metatarsals
O. phalanges
P. coxa
Q. sacrum
R. humerus
S. costal cartilage
T. true ribs
U. sternum
V. cervical vertebrae
W. thoracic vertebrae
X. lumbar vertebrae
Y. clavicle
Z. pectoral girdle
AA. scapula
BB. pelvic girdle
21. A. frontal bone
B. ethmoid bone
C. lacrimal bone
D. zygomatic bone
E. vomer
F. maxilla
G. mandible
H. parietal bone
I. temporal bone
J. occipital bone
K. sphenoid bone
L. nasal bone
