These small structures filter lymph and contain lymphocytes and macrophages
Lymph Nodes
The process by which a cell engulfs and destroys a pathogen.
Phagocytosis
The cells that support, protect, and nourish neurons.
Neuroglia (glial cells)
how many pairs of cranial nerves and spinal nerves:
This lymphoid tissue is found in the small intestine.
Peyer's Patches
A substance released during inflammation that promotes vasodilation and increases capillary permeability.
Histamine
The part of the peripheral nervous system that carries sensory information toward the CNS.
Sensory (afferent) division
The glial cells that form myelin around axons in the peripheral nervous system.
Schwann cells
This region of a lymph node contains lymphatic tissue and sinuses where lymph flows toward the exit.
Medulla
The four classic signs of inflammation are collectively known as the cardinal signs.
Redness, heat, swelling, and pain
The brain lobe primarily associated with hearing and memory.
Temporal lobe
The tough, outermost layer of the meninges that provides strong protection to the brain and spinal
Dura mater
A patient has impaired lymphatic drainage from the lower limbs and abdominal region. The nurse explains that lymph from these areas collects in an enlarged sac-like structure located in the abdomen before continuing upward through the thoracic duct. Which structure is being described?
Cisterna chyli
A newborn receives protective antibodies from the mother through breast milk. What type of immunity does the newborn acquire?
Naturally acquired passive immunity
The gaps between segments of the myelin sheath along an axon.
Nodes of Ranvier
A patient experiences increased heart rate, pupil dilation, and increased breathing during a stressful event. Identify the nervous system division responsible.
Sympathetic division
A patient with extensive lymphatic obstruction develops edema in both lower extremities. The nurse understands that lymph from both lower limbs normally drains into the:
A. Right lymphatic duct
B. Thoracic duct
C. Subclavian vein directly
D. Right lymphatic capillaries
Thoracic duct
A patient with allergic asthma experiences bronchoconstriction after exposure to an allergen such as dust mites or pollen. Which immunoglobulin is primarily involved in triggering this allergic response?
IgE
A patient suffers damage to the medulla oblongata. Which vital function is most likely to be severely affected?
Regulation of breathing and cardiovascular function
A patient is assessed after a stroke and is noted to have difficulty swallowing, hoarseness, and a reduced gag reflex. The nurse recognizes that these findings are associated with dysfunction of which cranial nerve?
A. Trigeminal nerve (CN V)
B. Facial nerve (CN VII)
C. Glossopharyngeal nerve (CN IX)
D. Hypoglossal nerve (CN XII)
Glossopharyngeal nerve (CN IX)
