Basic Nervous SYstem Anatomy

What does CNS and PNS stand for? Central Nervous System and Peripheral Nervous System!

What are the parts of the CNS? brain and spiral cord and it controls thinking, memory and behavior.

Describe something that you do on a regular basis that your PNS controls. carry messages through out the body.

What are the two divisions of the autonomic nervous system and what does each control? Sympathetic branch controls the body in times of stress, worry, fear,and emergency. Parasympatic branch brings the body back to a normal state and allows for rest and relaxation to occur.

What are the three main types of neurons? sensory neuron, motor neuron, and interneuron!
What is the function of each? interneuron only conducts within the CNS. motor neurons takes the impulse from the CNS to the foot for actions. sensory neuron conduct the impulse from the foot to the CNS.

What is the function of the axon of a nerve cell? The dendrite?

What is a synapse? simply the conduction of an impulse from one neuron to another.-Sketch a neuron and label the axon and the dendrite. (above)

Baisc Ear Anatomy Worksheet

1. Sketch a picture of an ear and label the following: (above)
Inner ear
middle ear
outer ear
pinna
tympanic membrane
cochlea
stapes
malleusincus
2. What is the function of the following:Pinna- cartilage flap that conveys sounds waves into the ear.
tympanic membrane - converts sounds waves into sound vibrations.

ossicles - three small bones which magnify sound vibrations

cochlea - contains fluid and changes sound vibrations into nerve impules.

semicircular canals - sends impulses to the brain to let it know your body is off balance.

3. What three bones make up the ossicles? - incus -stapes - malleus

4. What is the function of hairs in the ear? stimulate nerve impulses to be sent to the brain by way of the auditory nerve.

Basic Skeletal Anatomy Worksheet

1.Describe the 4 functions of bones. supporting the body, protecting internal organs, produce blood cells, and provide muscle attachment .

2.How many bones are there in the human body? 206

3.What are the two divisions of the skeletal system? Name 5 specific bones in each division.

4.What bone makes up the upper arm? humerus

5.What bone makes up the face? facial bone

6.Name two bones that protect vital internal organs. ribs, and vertebral column

7.What bone in the forearm is always on thumb side? radius

8. What bone is movable for back muscles to attach to?vertebral column

9. What bone is also known as the shin bone? tibia

10. Sketch a human skeleton and label the following bones: skull, clavicle, sternum, humerus, radius, ulna, patella, femur, tibia, fibula, pelvis, vertebral column, scapula and rib cage.

Basic Joint Anatomy Worksheet

1.Why is there little to no movement in a fibrous joint?Because the bones making up the joint are united with strong fibrous tissue.

2.What is an example of a fibrous joint? sutures which hold the bones in the skull

3.Describe a cartilaginous joint and give an example. where bones are united by intervening fibrocartilage- vertebrae of the spinal column are joined by intervertebral discs

4.What type of joint essentially allows free movement? synovial joints

5. What lubricates a joint cavity? Synovial fluid.

6.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.

7.Plane joint- synovial, gliding or slipping, slighlty curved articular surfaces, carpal bones in the hand

8.Hinge joint- synovial, movement is limited to rotate around a single axis, irregular cylinder and a concave groove, elbow joint

9.Condylar joint-synovial, similar to hinge but also as other movements, has 2 aticular surfaces, the knee joint

10.Ball and Socket joint- synovial, spherical articulation, movement in variety of directions, the shoulder joint

11.Ellipsoidal joint- synovial, oval ball and socket, variety of direct, wrist jointPivot joint- synovial, bony peg, rotate with respect to the other, joints between the radius and ulna

Saddle joint- synovial, 2 western saddles, articulating surfaces concave in one direction and convex in the other, movement in variety of directions, joint at base of the thumb.
