| Question | Answer |
|---|---|
| What is homeostasis? | Refers to stability, balance or equilibrium within a cell or the body. |
| What are biological molecules? | They are the ingredients of life. And are Carbohydrates, Lipids, Proteins and Nucleic acids. |
| Biochemical reactions | that continuously take place in a cell & all over the body, need a homeostasis state in order to function properly. |
| Synovial joints | are the most common and movable joints characterized by a fluid filled joint cavity e.g. the knee and hip |
| Muscle Contraction Mechanism | Excitation, Calcium Activation, Contraction, Relaxation |
| Autonomic Nervous System | Efferent pathways of the autonomic nervous system (ANS) carry information to the autonomic, or visceral, effectors, which are mainly the smooth muscles, cardiac muscle, glands, adipose tissue, and other “involuntary” tissue |
| The efferent pathways of the ANS | can be divided into the sympathetic division and the parasympathetic division. |
| The sympathetic division | is involved in preparing the body to deal with immediate threats to the internal environment. It produces the “fight-or-flight” response. |
| The parasympathetic pathways | coordinate the body’s normal resting activities. The parasympathetic division is thus sometimes called the “rest-and-repair” division. |
| EPITHELIAL TISSUE | Epithelial tissue, or epithelium, often is subdivided into two types: (1) membranous (covering or lining) epithelium and (2) glandular epithelium. |
| FUNCTIONS OF EPITHELIAL TISSUE | Protection, Protection, Sensory functions, Secretion, Absorption. Excretion |
