Central Nervous System (Brain; spinal chord) | Peripheral Nervous System (Peripheral nerves)
33
What are the functions of the Nervous system?
Directs immediate responses to stimuli, usually by coordinating the activities of other organ systems; provides and interprets sensory information about internal and external conditions
34
What are the structures of the Endocrine system?
Pineal gland; Pituitary gland; Thyroid gland; Parathyroid gland; Adrenal gland; Thymus; Pancreas; Ovary in females; Testis in males
35
What are the functions of the Endocrine system?
Directs long-term changes in activities of other organ systems
36
What are the structures of the Cardiovascular system?
Heart; Artery; Vein; Capillaries
37
What are the functions of the Cardiovascular system?
Transports cells and dissolved materials, including nutrients, wastes, oxygen, and carbon dioxide
38
What are the structures of the Lymphatic system?
Thymus; Lymph nodes; Spleen; Lymphatic vessel
39
What are the functions of the Lymphatic system?
Defends against infection and disease; returns tissue fluids to the bloodstream
40
What are the structures of the Respiratory system?
Nasal Cavity; Sinus; Pharynx; Larynx; Trachea; Bronchi; Lung; Diaphragm
41
What are the functions of the Respiratory system?
Delivers air to sites in the lungs where gas exchange occurs between the air and bloodstream; produces sound for communication
42
What are the structures of the Digestive system?
Salivary gland; Mouth, teeth, and tongue; Pharynx; Esophagus; Liver; Gallbladder; Stomach; Pancreas; Large intestine; Small intestine; Anus
43
What are the functions of the Digestive system?
Processes food and absorbs nutrients
44
What are the structures of the Urinary system?
Kidney, Ureter, Urinary bladder; Urethra
45
What are the functions of the Urinary system?
Eliminates waste products from the blood; controls water balance by regulating the volume of urine produced
46
What are the structures of the Male Reproductive system?
Prostate gland, Seminal gland, Ductus deferens, Urethra, Epididymis, Testis, Penis, Scrotum
47
What are the functions of the Male Reproductive system?
Produces male sex cells (sperm) and hormones
48
What are the structures of the Female Reproductive system?
Mammary gland, Uterine tube, Ovary, Uterus, Vagina, External genitalia
49
What are the functions of the Female Reproductive system?
Produces female sex cells (oocytes, or immature eggs) and hormones; supports embryonic and fetal development from fertilization to birth
50
Define homeostasis
The maintenance of internal environment within range suitable for cell activities.
51
What is the result if homeostasis is not maintained?
Sickness or even death
52
What are the 3 components in the body that are required to maintain homeostasis?
Receptor; Control Center (aka integration ctr); Effector
53
What is a receptor?
A body part that can sense change
54
What is a control center/integration ctr?
A body part that receives the information from the receptor and tells the body how to respond to the change (usually the CNS or Endocrine organs)
55
What is an effector?
Its the part that responds to the commands of the control center. The activity of the effector has an effect upon the stimulus. (Effectors include muscles & glands in the body)
56
What are the two types of feedback used to maintain homeostasis?
Negative feedback; Positive feedback
57
What is negative feedback?
A stimulus produces a response that opposes the original stimulus. (Most common type of feedback; used for conditions that need frequent adjustment)
58
What is positive feedback?
Initial stimulus produces a response that reinforces that stimulus.
59
Example of negative feedback: maintenance of body temperature
Receptor: Body's temperature sensors Control center: Thermoregulatory ctr in the brain Effector: Blood vessels & sweat glands in skin
60
Examples of positive feedback
Clotting when a blood vessel is damaged. Oxytocin release during childbirth.
61
Name the aspects of the anatomical position
1. Is standing erect 2. Feet are parallel, flat, & directed forward 3. Face & eyes are forward 4. Arms are held at the sides 5. The palms are facing forward with the thumbs directed away from the body
62
Define prone position
the body lying face down
63
Define supine position
the body lying face up
64
Name the anatomical directions when referring to the location of one anatomical structure in relationship to another.
``` Superior (cranial) vs. Inferior (caudal) Anterior vs. Posterior Ventral vs. Dorsal Medial vs. Lateral Ipsilateral; Contralateral; Unilateral Proximal vs. Distal Superficial vs. Deep ```
65
Define relation between Superior (cranial) and Inferior (caudal)
Superior (cranial): towards the head end or upper part of a structure or the body; above Inferior (caudal): away from the head; toward the lower part of a structure or the body; below
66
Define relation between Anterior (Ventral) and Posterior (Dorsal)
Anterior (Ventral): Toward or at the front ofthe body; in front of Posterior (Dorsal): Toward or at the back of the body; behind
67
Define relation between Medial and Lateral
Medial: Toward the midline of the body; on the inner side of Lateral: Away from the midline of the body; on the outer side of
68
Other lateral directions & what they reference
Ipsilateral - On the same side (affecting the arm and leg on the same side Contralateral - On opposite sides (affecting the right arm and left leg) Unilateral: in reference to only one side of the body
69
Define relation between Proximal and Distal
Proximal: closer to the origin of the body part or the point of attachment of a limb to the body trunk Distal: farther from the origin of a body part or the point of attachment of a limb to the body trunk
70
Define relation between Superficial and Deep
Superficial: (external) Toward or at the body surface Deep: (internal) Away from the body surface; more internal
71
What are the 3 anatomical planes?
Coronal (frontal) plane; Sagittal plane (median or midsagittal plane; parasagittal plane); transverse (horizontal) plane
72
Describe a coronal (frontal) plane
A vertical or longitudinal plane of sectioning (divides the body into anterior and posterior portions)
73
Describe a sagittal plane
A vertical or longitudinal plane of sectioning (divides the body or an organ into left & right portions)
74
Describe a median or midsagittal plane
The right and left portions are symmetric
75
Describe a parasagittal plane
The right and left portions are not symmetric
76
Describe a transverse (horizontal) plane
a horizontal plane of sectioning (divides the body or an organ into superior and inferior portions
