Answers
Four types of cells and tissue - CORRECT ANSWER✔✔-epithelial, connective,
| | | | | | | | | |
muscle, nervous |
Simple epithelium - CORRECT ANSWER✔✔-one layer of cells
| | | | | | |
Stratified epithelium - CORRECT ANSWER✔✔-more than one layer of cells
| | | | | | | | |
Characteristics of epithelial cells and tissues - CORRECT ANSWER✔✔-Specialized
| | | | | | | | |
for selective secretion and absorption of ions and organic molecules, surfaces
| | | | | | | | | | |
that cover the body or individual organs, cells are held together by tight junctions
| | | | | | | | | | | | |
Loose connective tissue - CORRECT ANSWER✔✔-Tissue that binds epithelia to
| | | | | | | | | |
underlying tissues and holds organs in place. Contains collagenous, elastic, and
| | | | | | | | | | |
recticular fibers. |
Dense connective tissue - CORRECT ANSWER✔✔-tough, rigid tissue that makes
| | | | | | | | | |
up tendons and ligaments
| | |
Bone - CORRECT ANSWER✔✔-Mineralized connective tissue.
| | | | |
,Cartilage - CORRECT ANSWER✔✔-A connective tissue that is more flexible than
| | | | | | | | | | |
bone and that protects the ends of bones and keeps them from rubbing together.
| | | | | | | | | | | | |
Adipose - CORRECT ANSWER✔✔-fat
| | |
Extracellular matrix - CORRECT ANSWER✔✔-Mixture of proteins, polysaccharides,
| | | | | | |
|minerals. Provides a scaffold for cellular attachments and transmits information
| | | | | | | | | |
in the form of chemical messengers to the cells
| | | | | | | |
Homeostasis - CORRECT ANSWER✔✔-A tendency to maintain a balanced or
| | | | | | | | | |
constant internal state; the regulation of any aspect of body chemistry, such as
| | | | | | | | | | | | |
blood glucose, around a particular level
| | | | |
positive feedback loop - CORRECT ANSWER✔✔-Causes a system to change
| | | | | | | | | |
further in the same direction.
| | | |
negative feedback loop - CORRECT ANSWER✔✔-Causes a system to change in the
| | | | | | | | | | |
opposite direction from which it is moving
| | | | | | |
homeostatic control system - CORRECT ANSWER✔✔-collection of interconnected
| | | | | | | |
components that keeps a physical or chemical variable of internal environment
| | | | | | | | | | |
within a predetermined normal range of values
| | | | | |
components of a reflex arc - CORRECT ANSWER✔✔-sensory receptor, sensory
| | | | | | | | | |
neuron, integrating center, motor neuron, effector
| | | | |
, Hormones - CORRECT ANSWER✔✔-Chemical messengers, mostly those
| | | | | | |
manufactured by the endocrine glands, that are produced in one tissue and affect
| | | | | | | | | | | |
another
|
Neurotransmitters - CORRECT ANSWER✔✔-chemical messengers that cross the | | | | | | | |
synaptic gaps between neurons
| | |
Paracrine molecules - CORRECT ANSWER✔✔-Acts on nearby cells
| | | | | | |
Autocrine molecules - CORRECT ANSWER✔✔-Acts on the same cell that secreted
| | | | | | | | | | |
the molecules
|
Adaptation - CORRECT ANSWER✔✔-A characteristic that improves an individual's
| | | | | | | | |
ability to survive and reproduce in a particular environment.
| | | | | | | |
acclimatization - CORRECT ANSWER✔✔-Physiological adjustment to a change in
| | | | | | | | |
an environmental factor
| |
circadian rhythm - CORRECT ANSWER✔✔-A physiological cycle of about 24 hours
| | | | | | | | | | |
that is present in all eukaryotic organisms and that persists even in the absence of
| | | | | | | | | | | | | |
external cues.
| |
Major elements of the human body - CORRECT ANSWER✔✔-Oxygen (O), Carbon
| | | | | | | | | | |
(C), Hydrogen (H), Nitrogen (N)
| | | |
