week 6-12
| What is the primary function of nervous system cells? | Neurons transmit signals, and glial cells support them, maintain homeostasis, protect, and assist neuron function. |
| What process describes the propagation of nerve impulses along a neuron | Nerve signaling involves action potentials along axons, neurotransmitter release at synapses, and receptor binding on target cells. |
| What structures constitute the central nervous system (CNS) ? | The brain and spinal cord, responsible for processing and integrating information. |
| What are the divisions and functions of the autonomic nervous system? | Sympathetic (“fight or flight”) and parasympathetic (“rest and digest”) divisions regulate involuntary body functions. |
| What are general senses and how are they detected ? | General senses—such as touch, pain, temperature, and proprioception—are detected by receptors distributed throughout the body. |
| What do the special senses include, and which organs correspond? | Vision (eyes), hearing and balance (ears), smell (nose), and taste (tongue). |
| How is endocrine regulation described? | Hormones released by endocrine glands travel via the bloodstream to distal target organs to regulate physiological functions. |
| What is the role of endocrine glands? | Glands like the pancreas, thyroid, and adrenals secrete hormones essential for metabolism, growth, stress response, and reproduction. |
| What are the key properties of blood? | Blood consists of plasma and formed elements—red cells, white cells, and platelets—and transports nutrients, gases, and waste |
| What is the basic structure and function of the heart ? | Four-chambered muscular pump; it circulates blood through pulmonary and systemic circuits with coordinated contractions. |
| What’s the process of the digestive system? | Enzymatic breakdown of nutrients in the small intestine and absorption of amino acids, fatty acids, sugars, vitamins, and minerals |
