Homeostasis
What is homeostasis?
I am a ligand. What am I?
A signaling molecule that binds to a specific receptor on the cell's membrane.
Refers to the limbs of the body.
What is Appendicular OR appendages.
Term that splits the body into right and left halves.
What is Sagittal.
What is the meninges?
The membrane that covers the brain and spinal cord.
How does dynamic equilibrium tie into homeostasis?
It is the range of and stability internal that occurs. It is balanced.
What are the steps of the signal transduction pathway?
1. Ligand binds to a specific receptor.
2. The signal is transduced throughout the cell.
3. The signal results in a response.
Where is the ventral body cavity?
Includes the chest to pelvis region
Houses the fragile organs of the body.
What is the Dorsal body cavity.
The parietal and visceral membranes are both considered a type of __________ membrane.
What is serous membrane.
What is negative feedback? Example.
Correction to take your body back to your range of homeostasis. Sweating when hot is an example.
What are some responses that can occur in the signal transduction pathway?
Opening of ion channels, alterations in gene expression, and alteration of enzyme activity
Explain what connective tissue does.
Used for insulation and protection, most commonly found type in the body, supports and binds, transport, and movement.
What does nervous tissue do for the body?
Allows us to have a response to stimuli.
I line your body surface and am dry. What am I?
What is the cutaneous membrane.
What is positive feedback? Example.
What are the four types of signals that can be sent in the transduction pathway?
Autocrine: impact the same cell that sends the signal
Paracrine: impacts nearby cells
Juxtacrine: impacts cells directly touching that cell
Hormones: travel to distant cells
What are the three types of muscle tissue called and what type of movement do they control?
1. Smooth muscle: involuntary
2. Cardiac muscle: involuntary
3. Skeletal muscle: voluntary
The thoracic cavity is found within which greater body cavity?
The ventral body cavity.
What is the thoracic cavity?
Includes the heart and lungs
Does homeostasis occur at only the organ/organ system level?
NO!! It happens at the cellular level as well by the signal transduction pathway.
What are the two types of receptors for the signal transduction pathway?
Intracellular: located inside of a cell
Membrane: located on the cell membrane
Provide 4 directional and/or regional terms to describe an injury location for someone with a left ankle injury.
Examples:
-Inferior region
- Distal region of the leg
- Proximal to the foot
- Lateral side of the ankle
What is the correct anatomical position?
Standing with feet slightly apart and arms at your sides; right and left are from THEIR perspective.
