What are the tiny artieries and veins that carry the blood to the retina called?

Back 3

Blood vessels

Front 4

What is the muscle that control the shape of the lens for near and far vision?

Back 4

Ciliary Body

Front 5

What is one type of photoreceptor cells in the retina?

Back 5

Cones

Front 6

What is the clear, tough covering over the iris and the pupil that helps protect the eye and begins focusing the light?

Back 6

Cornea

Front 7

Name the dimple in the retina where cones are concentrated and vision is most acute.

Back 7

Fovea

Front 8

What is the muscle that controls the amount of light that enters the eye. It is suspended between the cornea and the lens?

Back 8

Iris

Front 9

What is the clear, flexible structure that adjusts the eye's focus, allowing us to see objects both near and far? It is responsible for about 20% of our focousing.

Back 9

Lens

Front 10

What is the bundle of nerve fibers that carry information from the retina to the brain?

Back 10

Optic nerve

Front 11

What is the layer of light-sensitive cells lining the inner eyeball? It detects images focused on the back of the eye by the lens and the cornea. It is connected to the brain by the optic nerve.

Back 11

Retina

Front 12

What is one type of photoreceptor cells in the retina that respond to dim light?

Back 12

Rods

Front 13

What is the thick, tough, white covering of the eyeball?

Back 13

Sclera

Front 14

What are the fibers that connect the ciliary body to the lens?

Back 14

Suspensory ligaments

Front 15

What is the colorful, shiny material located behind the retina? It is found in animals that have good night vision, it reflects light back through the retina.

Back 15

Tapetum

Front 16

What is the thick, clear jelly that helps give the eyeball its shape?

Back 16

Viterous humor

Front 17

What part of the endocrine system has the following functions:
1-Considered master control center for the endocrine system
2-Secretes releasing and inhibiting hormones that control anterior pituitary gland
3-Produces hormones that are transported to and stored in posterior pituitary gland
4-Controls autonomic nervous system
5-Regulates body temp, food, and water intake
6-Regulates emotional behavior
7-Maintains sleep/wake cycle

Back 17

Hypothalams

Front 18

What part of the endocrine system has the following functions:
1-Secretes melatonin (involved in sleep/wake cycles)
2-Modified activity in endocrine organs (pituitary,pancreas,parathyroid,suprarenal,and gonads)

Back 18

Pineal gland

Front 19

What part of the endocrine system has the following functions:
1-Anterior pituitary produces the following hormones: thyroid-stimulatin (TSH),prolactin (PRL),adrenocorticotropic (ACTH),growth (GH),luteinizing (LH),melanocyte-stimulating(MSH),and follicle-stimulating (FSH)
2-Posterior pituitary stores and releases: antidiurectic hormone (ADH) and oxytocin (OT)

Back 19

Pituitary gland

Front 20

What part of the endocrine system has the following functions:
1-Synthesizes and secretes thyroid hormones T3 (triiodothyronine) and T4 (thyroxine)
2-Synthesize and secrete calcitonin
If this is enlarged it is known as goiter, typically due to insufficient dietary iodine

Back 20

Thyroid gland

Front 21

What part of the endocrine system has the following functions:
1-Exocrine:digestive enzymes (pancreatic juice) secreted by acinar cells and released into the duodenum via pancreatic ducts
2-Endocrine: (regulation of glucose metabolism): hormones (insulin,glucagon, and somatostatin) secreted by pancreatic islet cells and released into the blood

Back 21

Pancreas

Front 22

What part of the endocrine system has the following functions:
1-Cortex:secretes hormones (corticosteroids and androgent)
2-Medulla: chromaffin cells secrete catecholamines (epinephrine and norepinephrine)

Back 22

Adrenal (Suprarenal) glands

Front 23

What part of the endocrine system has the following functions:
1-Produces sperm cells
2-Produces androgens (male sex hormones) such as testosterone

Back 23

Testis

Front 24

What part of the endocrine system has the following functions:
1-Maturation (oogenesis) and release (ovulation) of oocytes
2-Produces the female sex hormones progesterone, estrogen, and inhibin

Back 24

Ovary

Front 25

What part of the endocrine system has the following functions:
1-Removes excess water, electrolytes, and wastes of protien metabolism from blood
2-Urine formation

Back 25

Kidney

Front 26

What part of the endocrine system has the following functions:
1-Involved in T-lymphocytes differentiation
2-Secretes thymopoietin and thymosins

Back 26

Thymus

Front 27

What part of the endocrine system has the following functions:
1-Composed of two cell types: cheif cells (or principle cells), which sythesize Parathyroid hormone and oxyphil cells, whose function is unknown.
2-PHT is secreted in response to low blood calcium leves
3-PHT raises calcium levels which increases calcium absorption from the small intestine
