Endocrine System

TermDefinition
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
