1

Endocrine glands produce

Hormones which in turn affect other tissues within the body

2

Pituitary gland has been called the

Master gland because it produces so many hormones that regulate the activity of other endocrine glands

3

The pituitary gland has two lobes

Anterior pituitary and posterior pituitary

4

Although the pituitary gland has been called the master gland, it is unfair to

The hypothalamus which is actually the master control center of the endocrine control system

5

Where are the thyroid and parathyroid glands located?

In the neck

6

Location, hormones, and basic function for hypothalamus

Location: In the inferior region of the diencephalon
Hormones: Antidiuretic hormone (ADH)
Oxytocin (OT)
Regulatory hormones
Basic function: Master control center of the endocrine system. Regulates most endocrine activity

7

Location and hormones, and basic function for the pituitary gland

Location: Inferior to the hypothalamus
Hormones for anterior pituitary lobe: Adrenocorticotropic hormone (ACTH)
Follicle-stimulating hormone (FSH)
Growth hormone (GH)
Luteinizing hormone (LH)
Melanocyte-stimulating hormone (MSH)
Prolactin (PRL)
Thyroid-stimulating hormone (TSH)
Hormones for posterior pituitary lobe:
Antidiuretic hormone (ADH)
Oxytocin (OT)
Basic function: small endocrine organ that controls a multitude of important functions in the body

8

Location and hormones, & basic function for the pineal gland

Location: Attached to the posterior region of the epithalamus
Hormones: Melantonin
Basic function: Influences daily biorhythms

9

Location, hormones, & basic function for the thyroid gland

Location: Inferior to the thyroid cartilage of the larynx and anterior to the trachea
Hormones: Calcitonin (CT)
Thyroid hormone (TH)
Basic function: Regulates metabolism, growth & development, lowers blood Ca+ level

10

Location, hormones, & basic function for the parathyroid glands

Location: Posterior surface of the thyroid gland
Hormones: Parathyroid hormone (PTH)
Basic function: Raises blood Ca++ level

11

Location, hormones, & basic function for the thymus

Location: Within the mediastinum superior to the heart and immediately posterior to the sternum
Hormones: Thymopoietin and thymosins
Basic function: Roles in immune response

12

Location and hormones for pancreatic islets

Location: Scattered among the pancreatic acini
Hormones: Glucagon, Insulin, Somatostatin, Pancreatic polypeptide
Basic function: Lowers blood sugar levels & raises blood sugar level

13

Location, hormones, & basic function for the adrenal (suprarenal) glands

Location: Anchored on the superior surface of each kidney
Hormones from cortex: Corticosteroids
Hormones from medulla: Epinephrine (E)
Norepinephrine (NE)
Basic function: Promotes protein breakdown & conversion to glucose, Na+ reabsorption, control of salt water balance, raises blood sugar & fatty acid levels; increases both rate & force of heart contractions, promotes constriction or dilation of blood vessels

14

Location, hormones, & basic function for the gonads testes

Location: Testicles
Hormones: Androgens and Inhibin
Basic function: Role in development of genitals & maintenance of male sexual traits, sperm formation, growth

15

Location, hormones, & basic function for the gonads ovaries

Location: ovaries
Hormones: Estrogen, Inhibin, Progesteron
Basic function: Role in development of genitals & maintenance of female sexual traits, growth, required for egg maturation & release, proliferation of uterine lining. Prepares & maintains uterine lining for pregnancy, stimulates breast development

16

What are the 6 extrinsic eye muscles?

1) Superior rectus
2) Inferior rectus
3) Medial rectus
4) Lateral rectus
5) Superior oblique w/trochela
6) Inferior oblique

17

What are the cutaneous receptors

1) Lamellated corpuscle
2) Bulb of krause
3) Free nerve ending
4) Corpuscle of touch
5) Hair root plexus
6) Organ of Ruffini

18

Location and function for Lamellated corpuscle

Location: Deep within the reticular layer of the dermis; in the subcutaneous layer of the palms of the hands, soles of the feet, breasts, and external genitalia; in the synovial membranes of joints; and in the walls of some organs
Function: Detect deep pressure and high-frequency vibration

19

Location and function for Bulb of krause

Location: Near the boarder of the stratified squamous epithelium in the mucous membranes of the oral cavity, nasal cavity, vagina, and anal canal
Function: detect light pressure stimuli and low-frequency vibration
