Clinical Anatomy: Nervous System Divisions Flashcards
1
Q
- Thoracolumbar Division
- Expends energy and deals with stressful and emergency situations
- Fight or Flight
- Preganglionic fibers originate from T1 through L2
A
Sympathetic Division
2
Q
- Craniosacral Division
- Converses energy and is active under normal, restful conditions, including digestion
- Preganglionic fibers originate from the brainstem and spinal cord from segments S2 and S4
A
Parasympathetic Division
3
Q
Consists of specialized tissues (glands) that secrete hormones directly into the vascular system
A
Endocrine System
4
Q
Secrete substances into ducts which drain to internal or external body surfaces
A
Exocrine Glands
5
Q
Feedback that controls most hormone secretion allowing concentrations to remain relatively stable
A
Negative Feedback
6
Q
What Hormones Regulate
A
- Reproduction
- Development
- Growth
7
Q
Attaches hypothalamus and pituitary gland
A
Infundibulum
8
Q
The Master Gland because of its many roles
A
Pituitary Gland
9
Q
Hormones secreted by the ANTERIOR pituitary gland
A
- Growth Hormone
- Prolactin
- Thyroid Stimulating Hormone
10
Q
- gland controlling metabolism and calcium levels in the blood
- located anterior to the trachea
A
Thyroid Gland
11
Q
Hormones secreted by the thyroid gland
A
- T3
- T4
- Calcitonin
12
Q
- 2 pairs of glands located on the posterior aspect of the thyroid glands
- secrete hormones that help regulate calcium and phosphate ions in the blood
A
Parathyroid Glands
13
Q
- Glands located on the superior poles of the kidneys
- Inner medulla secretes epinephrine and norepinephrine
- Cortex secretes hormones that control electrolytes, metabolism, and sex hormones
A
Adrenal Glands (suprarenal glands)
14
Q
- Dual gland with both endocrine and exocrine functions
- Endocrine parts secretes insulin and glucagon
- Exocrine part secretes digestive juice through the pancreatic duct into duodenum of SI
- Located posterior the stomach
A
Pancreas
15
Q
- Small gland located near the thalamus
- Secretes melatonin
A
Pineal Gland
