adult?

infancy and childhood? What affects how many sweat glands become active?
How does aging affect skin? Why are the elderly more sensitive to the cold? How
does UV exposure age skin?
Bone Tissue:
What two major types of cartilage are important in the skeleton? Where are
they found? How do they function?
What are the functions of bone? What substances can bone store?
Know the classification of bones: long, short, flat, irregular, sutural (wormian)
and
sesamoid, and examples of each. Where do sesamoid bones form, and what do they
do?
Know the parts of the long bones -diaphysis, epiphysis, periosteum, marrow (medullary)
cavity, etc .
Know what a tuberosity, crest, meatus, sinus, foramen, head and condyle mean for
bones. Know the terms in table 9.1 in your lab manual.
What are the four types of bone cells, and which one comes from a difference
source? What is that source? What does each type of bone cell do? How are
osteocytes connected to each other, and why is this important?
What are the organic and inorganic components of the matrix of bone? How do they
each function?
What is the microscopic structure of compact bone? What is found in the central canal?
How do the collagen fibers differ in alternating lamellae, and
what does this do for the bone?
How does the microscopic structure of spongy bone differ from that of compact
bone? (hint: what is missing?) How do the osteocytes here get nutrients?
