Anatomy & Physiology (161)

Question 1

What is anterior/ventral referring to in the anatomical position?

Answer 1

the front of the body

Question 2

What is inferior/caudal referring to?

Answer 2

Below or towards the feet

Question 3

What is posterior/dorsal referring to?

Answer 3

the back of the body

Question 4

Proximal/Distal - Feynman

Answer 4

Proximal and Distal refers to how close or far away the specific part is from where the limb attaches to?

Question 5

The toes are what from the ankles?

Answer 5

distal/inferior

Question 6

The knee is what from the hip?

Answer 6

distal

Question 7

Homeostasis- Feynman

Answer 7

homeostasis is the body’s regulation after a change of the environment (stimulus) either internally or externally?

Question 8

List 5 things the body regulates during homeostasis?

Question 9

Vasoconstriction/Vasodilation - Feynman

Answer 9

Vasodilation is the widening of blood vessels which leads to cooling of body while vasoconstriction closes the blood vessels which lead to heating

Question 10

List all body cavities

Answer 10

1. Cranial Cavity, b. Vertebral cavity, 2a. Superior mediastinum, c. Pleural, Pericardial cavity, e, diaphragm, 3. Abdominal, 4. Pelvic cavity, 5. Ventral cavity, 6. Abdominal-pelvic cavity

Question 11

What specific cavity does the heart reside in?

Answer 11

Pericardial

Question 12

List all planes of the body anatomically?

Answer 12

Sagittal, Frontal, Transversal

Question 13

Medial/Proximal- Feynman

Answer 13

Medial is referring to the midline of the body and proximal is away from the midline of the body

Question 14

What cavities make up the dorsal cavitiy?

Answer 14

Vertebral and Cranial Cavitiy

Question 15

What cavities make up the ventral cavity?

Answer 15

Thoracic Cavity, Abdominal cavity, Pelvic Cavity.

Question 16

What cavity do the lungs reside?

Answer 16

Pleural/thoracic

Question 17

Explain the processes of homeostasis

Answer 17

change of environment occurs (stimulus)-> receptor (picks up change of environment) -> sends to control center (tells what specific value) -> effector (makes change)

Question 18

Negative Feedback vs Positive Feedback- Feynman

Answer 18

when body counteracts against specific function that takes away from setpoint and bring it back that is negative feed back positive feedback is wanting more of variable

Question 19

Endocrine System- Feynman

Answer 19

The endocrine system is made up of glands that release hormones into bloodstream, hormones are chemicals that have specific functions in the body

Question 20

Ductless vs Ducts

Answer 20

Endocrine glands are ductless - meaning they release hormones through the blood stream While exocrine have ducts meaning they release their hormones exterior/ski

Question 21

Hormones - Feynman

Answer 21

horomones are checmials that order specific funtions in the body

Question 22

List 5 functions of the Endocrine System

Answer 22

Regulate homeostasis, move/secretes hormones into bloodstream, communication with body, manages stress, growth and development

Question 23

Isotopes- Feynman

Answer 23

Same element with different number of neutrons which cause new particles to be created

Question 24

Radioisotopes- Feynman

Answer 24

when nucleus becomes unstable with too many protons/neutrons

Question 25

Radioactive decay- feynman

Answer 25

is the process when radioactive isotope attempts to rearrange itself

Question 26

Names of radiation emitted during decay?

Answer 26

Gamma, Beta, Alpha

Question 27

Half Life- Feynman

Answer 27

Half life is the time it takes for one half of a radioisotope to decay

Question 28

How do you calculate atomic number?

Answer 28

Number of protons in nucleus

Question 29

How do you calculate atomic mass?

Answer 29

Number of protons/nuetrons

Question 30

Covalent bonds

Answer 30

when electrons are shared in an atom

Question 31

Ionic Bonds

Answer 31

when electrons are added or subtracted which form ions. opposite charges attract

Question 32

Cation

Answer 32

when atom loses an electron (becomes positive)

Question 33

Anion

Answer 33

when atom receives electron (becomes negative)

Question 34

Electrolytes in the body are ions are insoluble in water for hydrogen bonds covalently bonded

Answer 34

ions

Question 35

Element- Feynman

Answer 35

Atoms with the same amount of protons

Question 36

Molecules- Feynman

Answer 36

when two or more atoms combine chemically
