Describe the structure of smooth muscle.
Give this one a try later!
Smooth muscle is made up of spindle-shaped cells with a single nucleus
and no striations.
What is the apical surface of epithelial tissue?
Give this one a try later!
The free surface exposed to the body exterior or cavity
,Examples of each type of epithelium
Give this one a try later!
Simple squamous epithelium: Lining of blood vessels, alveoli in the lungs
Simple cuboidal epithelium: Kidney tubules, glandular ducts
Simple columnar epithelium: Lining of the stomach and intestines
Stratified squamous epithelium: Outer layer of the skin (epidermis)
Pseudostratified columnar epithelium: Lining of the respiratory tract
Stratified cuboidal epithelium: Excretory ducts of salivary and sweat glands
Stratified columnar epithelium: Conjunctiva of the eye
What must happen for the cervix to return to its normal size after childbirth?
Give this one a try later!
The positive feedback loop must be interrupted, typically by the
completion of childbirth, allowing the body to initiate healing and recovery
processes.
What is the integument's role in secretion and absorption?
Give this one a try later!
It secretes sebum for lubrication and sweat for cooling; absorbs topical
substances.
Is the system involving calcitriol an example of negative or positive feedback?
,Give this one a try later!
Negative feedback.
Why do people appear flushed when exercising on a hot day?
Give this one a try later!
Blood vessels dilate to increase blood flow, releasing heat and causing
redness.
What are the two types of connective tissue proper?
Give this one a try later!
Loose connective tissue and dense connective tissue.
Q4
What happens to calcium levels if you are vitamin D deficient, and how does this
affect PTH release?
Give this one a try later!
Calcium levels decrease, leading to increased PTH release.
What happens to bone density if osteoblasts outpace osteoclasts?
, Give this one a try later!
Bone density increases.
Define stimulus in the context of a homeostatic system.
Give this one a try later!
Change in internal and external environment that is detected by a
sensor/receptor
What are the functions of nervous tissue?
Give this one a try later!
Transmitting electrical signals, processing information, and coordinating
bodily functions.
Define a joint.
Give this one a try later!
A joint, or articulation, is where two or more bones meet.
How does mechanical stress affect bone remodeling?
