Stimulus

A

Changes in a variable that is regulated (e.g., temperature, stretch in muscle).

135
Q

Control Center

A

Structure (usually the brain or endocrine gland) that integrates input and then initiates change through the effector(s).

135
Q

Receptor

A

Structure that detects the stimulus (e.g., sensory neurons in the skin, stretch receptor in muscle).

136
Q

Effector

A

Structure (e.g., muscle or gland) that brings about a change to the stimulus.

137
Q

Negative Feedback

A

Control mechanism that keeps a variable within normal levels, the resulting action is always in the opposite direction of the stimulus, maintaining the variable within a normal level/set point.

137
Q

Positive Feedback

A

Control Mechanism that increases the original change in a variable, the stimulus is reinforced to continue in the same direction until a climactic event occurs, after which the body returns to homeostasis.

137
Q

How do homeostatic mechanisms regulated by negative feedback detect and respond to environmental changes?

A

Receptors detect stimulus, receptors send information to brain, Hypothalamus of Bain compares sensory input regarding stimulus, hypothalamus directs a response to effectors, effectors make a change in order to bring the body back to the set point.

138
Q

What is the general relationship of maintaining homeostasis to health and disease?

A

Maintaining homeostasis keeps the human body in good health and prevents disease, it is when homeostatic systems fail that disease occurs.

139
Q

Matter

A

A substance that has mass and occupies space.

140
Q

What are the three forms of matter?

A

Solid, liquid, and gas.

141
Q

What re atoms composed of?

A

Three subatomic particles

142
Q

What are the three subatomic particles that atoms are composed of?

A

Protons, neutrons, and electrons.

143
Q

Protons

A

Located in the nucleus of the atom, have a positive charge.

144
Q

Neutrons

A

Located in the nucleus of the atom, have a neutral charge.

144
Q

Electrons

A

Located in the Electron Shell/Energy cloud of the atom, have a negative charge.

145
Q

How are elements arranged in the periodic table based on atomic number?

A

Going from right to left, top to bottom, the atomic mass increases with each element on the periodic table.

145
Q

Isotope

A

Atoms of the same element that have the same number of protons and electrons, but differ in the number of neutrons.

145
Q

Radioisotopes

A

Unstable forms of an isotope, due to the fact that their nuclei contain an excess number of neutrons, making them radioactive.

146
Q

What is the octet rule?

A

Most atoms obtain an outer shell with eight electrons and gain chemical stability through the loss, gain, or sharing of electrons.

146
Q

How are elects organized in the periodic table based on the cadence electron number?

A

Each column of elements is assignment a number of valence electrons, they are numbered 1 through 8, left to right.

147
Q

Ion

A

An atom, or group of atoms, with a positive or negative electrical charge.

148
Q

Cations

A

Ions with a positive charge.

149
Q

Anions

A

Ions with a negative charge.

149
Q

List common Cations in the body?

A

Sodium Ion, Potassium Ion, Calcium Ion, Magnesium Ion, and Hydrogen Ion.

150
Q

List common anions in the body.

A

Chloride ion, bicarbonate ion, and phosphate ion.

151
Q

Ionic Bonds

A

Positively charged cations and negatively charged anions that have binded together by electrostatic interactions.

151
Q

Describe an ionic compound of NaCl.

A

Each sodium atom loses one outer shell electron to a chlorine atom, the sodium atom then becomes a sodium ion and the chlorine atom becomes a chloride ion, the oppositely charged Na+ and Cl- are held together by ionic bonds.

151
Q

Give an example of a molecular formula.

A

H2CO3

151
Q

Molecular Formula

A

The number and types of atoms composing. molecule.

152
Q

Structural Formula

A

The structural formula of a molecule is complementary to its molecular formula and exhibits not only the numbers and types of atoms, but also their special arrangements within the molecule.

153
Q

What are structural formulas helpful for and why?

A

Structural formulas are helpful for highlighting the difference between isomers because they demonstrate the structure, instead of just he number of each type of molecule.

154
Q

Polar Amino Acids

A

Contain R groups with elements in addition to Carbon and Hydrogen.

154
Q

Nonpolar Amino Acids

A

Contain R groups with either hydrogen or hydrocarbons.

155
Q

Charged Amino Acids

A

Amino acids with negatively charged R group include glutamate and asparate and those with a positively charged R group include histidine, lysine, and arginine.

155
Q

Amino Acids with Special functions

A

Proline, cysteine, and methionine have unique characteristics.
