Basic Nervous system worksheet
What does CNS and PNS stand for? Central nervous system Peripheral nervous system
What are the parts of the CNS? The brain and spinal cord
Describe something that you do on a regular basis that your PNS controls. Eat and breathe
What are the two divisions of the autonomic nervous system and what does each control? The autonomic nervous system is divided into two parts the sympathetic and the parasympathetic nervous system
What are the three main types of neurons? What is the function of each? sensory neuron- takes impulse to CNS, motor neuron-leaves first neuron and now is traveling within the CNS, interneuron-takes the response impulse from the CNS for an action
What is the function of the axon of a nerve cell? The dendrite? The axon is the sending end of the neuron and the dendrite is the receiving end of the neuron.
What is a synapse? Transfers the impulse from one neuron to another.
Sketch a neuron and label the axon and the dendrite

Article on steroids
Steroids, half of the MLB players are using them, unlike the NBA or NFL both which ban and test the use of steroids. The NHL does neither and the MLB has no steroid policy. Basically the players in the baseball leauge and the hockey leauge can use steroids and won't be punished for using them.Steroids has helped build the best slugging era the game of baseball has ever seen. No one denies that it is a problem but it is. In the MLB they don't have the right to test players for steroids, so i say let them use the steroids because after all it is their body.
There is a mental edge that comes with the use of steroids and it makes you more intense. If it was up to me i would ban the use of steroids because to me it's like cheating. That's my opinion and everyone is entitled to one but i feel like if you have to use steroids then you are no type of pro player. I feel if you use steroids you are cheating yourself and your fellow players. With that said i think they should test for steroids in all sports pro and college.

Basic Joint Anatomy Worksheet
Why is there little to no movement in a fibrous joint? Because the bones that make up the joint are united with fibrous tissue
What is an example of a fibrous joint? The sutures which hold together the bone of the skull
Describe a cartilaginous joint and give an example. Two or more bones joined by Cartilage. The vertebral column.
What type of joint essentially allows free movement? Synovial joint
What lubricates a joint cavity? Synovial fluid
For the following joint types please list the name of the joint type, the type of movement of the joint, the shape of the joint and an example.
Plane joint – glidding, slipping synovial and slightly curved
Hinge joint – two bones joined where the convex end of one bone fits into the complementary concave end of another
Condylar joint –two articular surfaces on each bone known as condyless similar to a hinge joint but also permits other kind of movement
Ball and Socket joint –a bone with a spherical mass on one end joined with a bone possessing a complementary hollow depressions
Ellipsoidal joint – permits movement in a variety of directions
Pivot joint – the end of a bone moving within a ring formed by another bone and connective tissue
Saddle joint- two bones joined each with a convex and concave surface that are complementary.

More about Skin worksheet
(1)What is pigmentation? What layer of skin is it associated with? What are the benefits of pigmentation? What are the disadvantages of pigmentation? Skin pigmentation is a disorder that affects the color of your skin. Pigmentation is associated with the epidermis layer of the skin. Some benefits of pigmentation is being able to keep a year round tan because we must reclaim our birthright. Uses of skin graft has inherent disadvantages of mismatched pigmentation between the graft and the surrounding skin and scar formation.
(2)What is botox? What are some of the disadvantages with botox? Would you be willing to risk the harmful effects of botox for your self image? Botox is the brand name of a toxin produced by the bacterium, clostridium, Botulinum in large amounts also known as food poisoning. Disadvantages of Botox is its non sustainability Botox wears off. Costs and inconvenience mount when an apparently simple procedure becomes a regular need. I would not want to risk my health for the harmful affects of botox.
(3)Do all of the products that claim to improve the quality of your skin work? What evidence did you find to support this? Are there any specific products that seem to be more effective than others according to your research? Which ones? Why are they more effective? What were your sources for this information? Could there be possible biases in the information you collected? What are these biases? Why do you think people spend millions of dollars a year on skin care products?
(4)What is balding? Is there a medical term for it? Are there treatments? Do they work? Balding is the state of lacking hair where it usually grows. The medical term for balding is Androgenic Alopecia or Male Pattern Baldness. There are many treatments for male and female balding. Do they work that’s a good question I think they do because it’s plenty of men who use Rogain and they like it.

pg 193 & 194
(4). List six functions of the skin? The skin protects, helps regulate body temperature , houses sensory receptors, synthesizes chemicals, and excretes waste.

(8)List the layers of the epidermis? Stratum corneum, stratum wadum, stratum granulosum,stratum spinosum, and stratum basle.
(13)Distinguish between the hair and hair folicle?
