Test Review
1. Tissues - type of tissue is present in specific areas of the body - anal canal
2. Matching - homeostasis - stimulus: produces change in variable,
receptor: detects change/responds to stimuli,
control center: determines set point for variable and receives input from receptor,
effector: provides the means to respond,
variable: is what's being maintained in homeostatic balance.
3. Active - sodium pumps and potassium - which areas of the cycle require ATP - Na+ diffuses in
and is pumped out. K+ is pumped in and K+ diffuses out. They are diffused by channel mediated
facilitated diffusion. Pumped in/ out is primary active transport. (require energy)
4. Characteristics of Dense Irregular CT - Bundles of collagen are thicker and irregularly arranged.
Where in the body? Dermis of skin, Joint capsules, fibrous covering of some organs.
5. Proximal: Closer to the point of the attachment - Distal: Further from point of attachment
6. Characteristics of the plasma membrane- Flexible outer boundary of cell and selectively
permeable. What does it contain? It's a bilayer made of polar/non polar molecules. Hydrophilic
heads (polar) and hydrophobic fatty acid tails (non polar). Act as a barrier to protect the cell, only
allowing what's necessary in.
7. Simple diffusion: Movement unassisted, lipid soluble solutes diffuse directly through membrane.
8. Tissues- simple columnar: One layer, elongated - simple squamous: one layer, flat - simple
cuboidal: one layer, square like - stratified squamous: multiple layer, flat/squashed, in epidermis
or moth, esophagus, anus- Pseudostratified columnar: False stratified, really simple (1 layer) cells
are just elongated - in trachea.
9. Serous membrane: secrete serous fluid, thin protective double membrane (parietal and visceral),
Why do we need fluid there? To reduce friction between organs.
10. Tissues- on playposit question- What specific cells are secreting ground substance?
11. Frontal/ Coronal Plane: Posterior- towards the back, Anterior- towards the front.
12. Ch3- Cellular extension: cilia, microvilli gap junctions, tight, desmosomes
13. Cranial Cavity, Thoracic Cavity, Abdominal Cavity - Ex of organs found in body cavities
14. Characteristics of epithelium tissue: polarity, specialized connections (tight junctions,
desmosomes), supported by CT, avascular but innervated, regeneration
15. Superior: above and Inferior:below - ex the heart is superior to the liver.
16. transporting mechanism: Osmosis, Carrier mediated diffusion, etc
17. Serous Membrane: They surround the organs - what tissue they're made of? Simple squamous -
epithelium
18. 4 Tissue Types: Muscle Tissue, Epithelial Tissue, CT, Nervous Tissue
19. Principle of complementarity structure and function. Anatomy- study of structure,
Physiology- study of function
20. Facilitated diffusion, simple diffusion? Which one needs energy? Which are high to low?
21. Tissue- Is skin an Organ? yes
22. Negative feedback loop? Reduces intensity of the og stimulus. How does it shut down the system
once it has reached homeostasis? by detecting the change in the regulated variable and initiating a
response that counteracts the initial change.
