QuestionAnswer
1.These convert stimuli into nerve impulses and conduct these impulses to muscle tissue or glands neurons1
2.Its main function is to propagate nerve impulses towards another neuron, muscle fiber, or gland. axon2
3.A region where communication occurs between 2 neurons, a target cell, or skeletal musclesynapse3
4.Short, tapering, and highly branched extensions off the cell body.dendrites4
5.Structure inside the cell body. neuclus5
6.Go back to the science lab and show Ms Andersson where the "nodes of ranvier" are on the diagram of the neuron. nodes of ranvier6
7.What is the function of the pupil? to let light into your eye7
8. What is the Function of the Aqueous Humor? A clear fluid that helps the cornea keep it's rounded shape8
9.What is the Function of the Sclera? Thick, tough, white outer covering of the eyeball9
10.Go back to the science lab and show Ms Andersson where the "blind spot" is on the eye model. blind spot10
11. What is the Function of the Cornea? It helps protect the eye and begins bending light11
12. What is the Function of the Iris? It controls how much light enters the eye12
13. What is the the Blind Spot of the Eye? The place where the optic nerve leaves the retina13
14. What is the Function of the Lens? Clear flexible structure, makes an image on the eye's retina14
15. What is the Function of the Vitreous Humor? Thick, clear jelly, helps give the eyeball it's shape15
16. What is the Function of the Tapetum? Colorful, shiny, located behind retina, gives night vision16
17. What is the Function of the Optic Nerve? Bundle of nerve fibers, carry information from the retina17
18. What is the Function of the Retina? Layer of light-sensitive cells, detects images18
19. Go back to the science lab and show Ms Andersson where the "retina" is on the eye model.Retina19
20. What is Vasoconstriction?Narrowing of blood capillaries restricting heat loss20
21. What is shivering? Involuntary reflex activating skeletal muscle21
22. What is Piloerection? Hairs stand up producing a better insulating layer22
23. What is Vasodilation? Enlarging of blood capillaries allowing heat loss23
24. Which of the following processes do not help in helping the body increase in temperature? a.Shivering b.Piloerection c. sweating sweating24
25. List two things you can do to reduce heat? sweating, vasodilation25
26. Which organ releases the largest amount of heat during vigorous exercise? muscles26
27. Is it true or false that temperature homeostasis fails if the environmental temperature is above 37 degrees Celsius.true27
28.Go back to the science lab and show Ms Andersson where the "dendrites" are on the diagram of the neuron.dendrites28
29.Which lobe of the brain is responsible for higher-order thinking? Frontal lobe29
30. This lobe is associated with hearing.temporal lobe30
31. This lobe is associated with sight.occipital lobe31
32. This lobe is associated with sensing temperature. parietal lobe32
33. This lobe is associated with sensing perceiving pain.parietal lobe33
34. This lobe is associated with planning and emotions. Frontal lobe34
35. Lesions on this lobe can cause visual hallucinations.occipital lobe35
36. This lobe is responsible for integrating sensory information. parietal lobe36
37. This lobe is located at the front of the brain. Frontal lobe37
38. Go back to the science lab and show Ms Andersson where the "parietal lobe" is on the skeleton parietal lobe38
39.This lobe is much more developed in humans than most other animals.Frontal lobe39
40. This lobe, along with the hippocampus, is involved with memory creation. temporal lobe40
41.This lobe governs spatial relationships. parietal lobe41
42.This lobe houses the primary visual cortex. occipital lobe42
