Endocrine System
Term | Definition |
---|---|
What occurs from spinal segments T1-L2 | Sympathetic preganglionic fibers join at the ventral root of each spinal nerve |
Effects of the Sympathetic Division: Eye | Dilation of pupil, secretion of tears. |
Effects of Sympathetic Division: Skin | Increase secretion of sweat glands, growth of hairs. |
Effects of Sympathetic Division: Adrenal Glands | Secretion of epinephrine and norepinephrine from adrenal medulla. |
Effects of Sympathetic Division: Respiratory System | Increase rate. |
Effects of Sympathetic Division: Digestive System | Decreases activity. |
Effects of Sympathetic Division: Skeletal Muscles | Increase in force of contraction and glycogen breakdown. |
Effects of Sympathetic Division: Adipose Tissue | Lipid breakdown and fatty acid release. |
Effects of Sympathetic Division: Urinary System | Decrease in urine production, relax in bladder. |
Effects of Sympathetic Division: Reproductive System | Increase in secretions male and female. |
Effects of Parasympathetic Division: Eye | Constriction of pupil. |
Effects of Parasympathetic Division: Skin | not innervated. |
Effects of Parasympathetic Division: Cardiovascular System | Decreases heart rate. |
Effects of Parasympathetic Division: Adrenal Glands | Not innervated |
Effects of Parasympathetic Division: Respiratory System | Decrease in rate |
Effects of Parasympathetic Division: Digestive System | Increase in activity, glycogen synthesis. |
Effects of Parasympathetic Division: Skeletal System | Not innervated |
Effects of Parasympathetic Division: Adipose Tissue | Not innervated |
Effects of Parasympathetic Division: Urinary System | Increase urine production, tenses bladder. |
Effects of Parasympathetic Division: Reproductive System | Erection of penis, or clitoris. |
Effects of Sympathetic Division: Cardiovascular | Increase in heart rate. |
The effects of neurotransmitters of adrenal medulla are similar to those produced by stimulation of: | Sympathetic Post ganglionic |
The integrative centers for the autonomic nervous system are located in: | The hypothalmus |
High thyroid stimulating hormone (THS) concentration in the blood means: | There is low concentration of thyroid hormones |
Rise in concentration of solutes in the blood or a fall in blood volume will cause a release of: | ADH hormone (antidiuretic) |
Iodine stimulates the formation of this hormone | Thyroxine (T4) |
Damage to beta cells results in: | Decreased: Glucose uptake, ATP production, Glycogen production, protein synthesis. |
Sympathetic nervous system provokes which response: | Fight or Flight |
The medulla secretes what hormones: | Epinephrine and norepinephrine |
Anterior Pituitary gland secretes: | ACTH, TSH, GH, PRL, FSH, LH, MSH |
Posterior Pituitary Glad secretes: | ADH and Oxytocin |
Thyroid secretes: | T3, T4, and CT |
Parathyroid secretes: | PTH |
Thymus secretes: | Thymosins |
Pancreas secretes: | Insulin and Glucagon |
Adrenal Gland Cortex secretes | Cortisol, corticosterone, aldosterone, and androgens |
Pineal Gland secretes: | Meletonin |
Overies secrete: | Estrogen, Progestins, and inhibin |
Testes secrete: | Androgens (including testosterone) and inhibin |
What fibers usually release norepinephrine (NE) | Sympathetic postganglionic |
What division of autonomic nervous system stimulates tissue metabolism: | Sympathetic division |
What is Dual Innervation | An organ receiving both sympathetic and parasympathetic nerves |
What is a preganglionic neuron: | An autonomic motor neuron whose cell body lies in the CNS |
