Lab Exam 1 Tissues

Question 1

Answer 1

simple squamouse

• easy trans membrane movement
• Mediators of filtration

Question 2

Answer 2

cuboidal

• lining a lumen kidney
• excretion
• secretion
• absorption

Question 3

Answer 3

stratified squamous epithelium (keratinized and non keratinized)

• lines tissues
• protection against wear and tear.
• keratinized is found on the skin
• non-keratinized is found lining the esophagus

Question 4

Answer 4

columnar epithelium lines

• lines most organs like the digestive tract and intestines
• protection
• secretion
• absorption

Question 5

Answer 5

ciliated pseudostratified columnar epithelium

• found on the trachea
• the hair trap dust and bacteria and bring it back up
• epithelial cilia work in tandem with goblet cells to propel mucus away from the lungs
• Protection

Question 6

Answer 6

CT : dense fibrous connective tissue

Regular:

• collagen fibers densely pack in
• found in ligaments and tendons

Question 7

Answer 7

CT : dense fibrous connective tissue

irregular :

• dense network of collagen and elastic fibers.
• found in join capsules,
• surrounds muscle fibers and the dermis of the skin

Question 8

Answer 8

loose ( areolar) CT -

• loose meshwork of collagen, elastic, and reticular fibers.
• found in mucous membranes, blood vessels, nerves, and organs.

Question 9

Answer 9

adipose tissue - fatty

• specialized for Fat synthesis
• breakdown and storage

Question 10

Answer 10

muscle (skeletal - look for striations!

• Striated
• Voluntary
• Each fiber forms by fusion of embryonic myoblasts
• Individually controlled
• Lines up in parallel with other fibers to form bundles

Question 11

Answer 11

cardiac muscle - look for Y shapes

• intercalated discs ( cardiac muscle) provide mechanical and electrical interconnections
• Are short
• striated
• Involuntary
• Branched to form Continuous fabric
• Not individually controlled

Question 12

Answer 12

smooth muscle

• nuclei seemed trapped
• Helps push out (urine, giving birth, blood flow)
• Not striated
• Involuntary
• Controlled by ANS

Question 13

Answer 13

giant multipolar neuron

• Neurons and glial cells
• Neurons are specialized for conducting electrical
• Have cell body, dendrites and axon

Question 14

Bone tissue

Contains 3 cell types

Answer 14

• Formed as concentric layers of calcified material
• Osteoblast: bone forming cells
• Osteocytes: trapped inactive osteoblasts
• Osteoclasts: the bone resorbing cells
