Question 1

anatomy

Answer 1

The study of the structure of body parts in their relationship to one another

Question 2

Gross anatomy

Answer 2

Can be seen with the naked eye

Question 3

Microscopic anatomy

Answer 3

Structures that cannot be seen with the naked eye

Question 4

Developmental anatomy

Answer 4

Traces structural changes that occur in the body throughout the lifetime

Question 5

Physiology

Answer 5

The study of the function of the body

Question 6

Gross anatomy

Answer 6

Has three subdivisions

Question 7

Region anatomy

Answer 7

All structures in that particular region of the body

Question 8

Systemic anatomy

Answer 8

Parts are studied by body system

Question 9

Surface anatomy

Answer 9

Study of internal structures as they relate to the overlying skin

Question 10

Microscopic anatomy

Answer 10

Has two divisions

Question 11

Cytology

Answer 11

The study of cells

Question 12

Histology

Answer 12

The study of tissue

Question 13

Developmental anatomy

Answer 13

Embryology which is the study of developmental changes of the body before birth

Question 14

Pathological anatomy

Answer 14

The study of structural changes caused by disease

Question 15

Radiographic anatomy

Answer 15

The study of internal structures visualize by specialist getting procedures such as x-rays MRI and CT scans

Question 16

molecular biology

Answer 16

The study of anatomical structures at subcellular level

Question 17

Levels of structural organization

Answer 17

Chemical: which is the atoms that combine to form molecules

cellular cells: are made of molecules

Tissue:consist of similar types of cells

Organ: which is made up of different types of tissues

Organ systems consist of different organs that work closely together

Organismal made up of the organ systems

Question 18

Organ systems

Answer 18

• Organ systems work cooperatively to perform necessary life functions
• Depend on organ systems to meet their survival needs.

Question 19

Homeostasis

Answer 19

Maintenance of a relatively stable internal environment despite continuous outside changes

A dynamic state of equilibrium

Question 20

Homeostatic control mechanism

Answer 20

• Involves continuous monitoring and regulation of many factors
• Nervous and endocrine systems accomplish the communication via nerve impulses and hormones

Question 21

Receptor/sensor

Answer 21

monitors the environment

Response to stimuli/changes and controlled variables

Question 22

Control center

Answer 22

Determined to set point at which the variable is maintained

Receives input from receptor

Determines appropriate response

Question 23

Effector

Answer 23

Receives output from control center

provides the means to respond

Response acts to reduce or enhance the stimulus feedback

Question 24

Negative feedback

Answer 24

Their response reduces or shut off the original stimulus
examples/
regulation of body temperature

regulation of blood volume by ADH

Question 25

Positive feedback

Answer 25

The response enhances or exaggerates the original stimulus

Question 26

Homeostatic imbalance

Answer 26

Disturbance of homeostasis:

• Increases risk of disease
• Contributes to changes associated with aging
