Lesson 1 Homeostasis Flashcards

1
Q

What are the 3 components to homeostasis?

A
  1. Detect the change (notice anything out of the ordinary)
  2. Integrations (analyze the problem)
  3. Response (brain interprets informations and signals the correct response to deal with the problem)

Q

What is positive feedback?

A

Occurs to increase change or output: the result of a reaction is amplified to make it occur more quickly.

Q

What is negative feedback?

A

Occurs to reduce the change or output: the results do the reaction is reduced to being the system back to the stable state. (More common)

A

Close to midline

31
Q

Lateral

A

Further from midline

32
Q

Superficial

A

On the surface

33
Q

Deep

A

Away from the surface or further into the body

34
Q

Proximal (limbs)

A

Closer to the center
Ex. Elbow is proximal to the wrist. The knee is proximal to the toes

35
Q

Distal (limbs)

A

Further away from the center of the body. Ex. The fingers are distal to the shoulder.

36
Q

A

Inferior

37
Q

Bone is _____ to the skin

A

Deep

38
Q

The abdomen is ____ to the head

A

Inferior

39
Q

The knee is_____ to the foot

A

Proximal

40
Q

The nose is_____to the ears

A

Medial or anterior

41
Q

The wrist is____to the elbow

A

Distal

42
Q

The sternum (breast bone) is______to the heart

A

Superficial

43
Q

The triceps are____to the biceps

A

Posterior

44
Q

The cervical (neck) vertebrae are_____to the lumbar(back) vertebrae

A

Superior

45
Q

Sagittal plane

A

Straight down the middle (left and right)

46
Q

Frontal plane

A

Cutting body from the front and the back

47
Q

Transverse plane

A

Cut in the middle, up and down sections

48
Q

Epithelial tissues

A

Provides protection, diffusion, secretory cells: located in the lining of the internal organs, skin.
Ex. Epidermis

49
Q

Connective tissue

A

Connects things, supports, fills spaces, stores energy throughout the body.
Examples: adipose biggest storage of energy/fat. Blood

50
Q

Muscle tissue

A

Causes movement which is attached to the bones, surrounding tubes, heart. Skeletal and cardiac muscle are striated. (Because actin and myosin contract repeatedly) Smooth muscle lack striated. (Because it’s too thick, not arranged in sarcomeres) like the GI system

51
Q

Nervous tissue

A

Sends information, controls body, senses environment, located in the brewing, spinal cord, and nerves
