Test U1 Intro To Anatomy Flashcards
- Cells that line the trachea specialize in moving liquids across their surfaces, down the throat. Which organelle would these cells most likely have in abundance
mitochondria
- Skeletal muscle is composed of very hardworking cells. Which organelles would you expect to find in abundance in a skeletal muscle cell.
nuclei
- Inherited traits are passed down form our parents to us, their offspring, by the information that is coded in our parents’
proteins
- To make a banana split, you halve a banana into two long , equal, right and left sides along the
transverse plane
- Is the most abundant and widely distributed in the entire human body.
epithelial tissue
- Used for insulation and protection
nervous tissue
- Responsible for body movements
connective tissue
- Lines the body cavities
connective tissue
- Allows us to respond to stimuli in our external environment
nervous tissue
- If a cell failed to go through DNA replication prior to mitosis, what would be the resulting issue with the daughter cells?
The daughter cells would have the wrong # of chromosomes (half the amount they should)
- White blood cells specialize in the engulfment and digestion of harmful substances, called pathogens. Which organelle do these cells most likely have in abundance to aid in accomplishing this task?
Lysosomes
- Salivary glands often specialize in packaging and secreting digestive enzymes in vesicles. Which organelle do these cells most likely have in abundance to aid in accomplishing this task
Golgi bodies
- List the levels of organization within an organism, starting with organism and simplifying from there
Organ system, organ, tissue, cell
- Transporting large molecules like glucose
Facilitated diffusion
- Transporting small molecules like O2 and CO2
Endocytosis

Molecular pump
- Low concentration of water
Hypotonic
- Causes a cell to swell
Hypertonic
- Describe the difference between how negative and positive feedback loops help to maintain homeostasis
A. How the output affects the input
B. A real world example in humans
A. In an negative feedback loop, the output of the system is a stabilizing response, returning the system to set a point. In a positive feedback loop, the output of the system amplifies the response, intensifying what is happening within the system.
B. Negative ex. How our bodies regulate our temp. Positive ex. Child birth
- List examples of two types of responses that can be triggered by a signaling pathway, such as the one picture in #39.
Opening of an ion channel
Alteration of an enzymes activity
43c. Includes the thoracic cavity
Dorsal
44b. During the examination, the doctor noticed an anterior rash that spread from just inferior to the nipple line to just superior of his pubic bone. What body parts did it cover?
Abdomin and pelvis
- Picture
Cardiac
Contracts the muscles of the heart to move blood throughout the body
Involuntary
- Picture
Skeletal
Makes up the muscles attached to bones that control our movements
Voluntary
- Picture
Smooth
Propels substances/ objects along internal passageways
Involuntary
