The 2 divisions of the Nervous System.
What is CNS and PNS?
Groups of cells
What is a tissue?
Kidney, ureter, urinary bladder, and urethra
What is urinary or excretory system?
The bodies ability to maintain relatively stable internal conditions.
What is homeostasis?
Structure that helps bacteria stick/attach to surfaces or other bacteria.
What is pilli?
Organs found in the CNS.
What is brain and spinal cord?
Organs Working together
What is an organ system?
Heart, blood vessels
What is cardiovascular?
If a runner is dehydrated, this feedback mechanism would kick in.
What is negative feedback?
The term that describes a microorganism that can cause disease.
What is a pathogen?
This makes up the PNS.
What are nerves?
All living things are made up of.
What is a cell?
Nasal cavity, pharynx, larynx, lungs, trachea, bronchus
What is respiratory?
This mechanism helps amplify the event and returns back to setpoint until event has stopped sending signals.
What is a positive feedback?
Viruses that infect bacterial cells are called this.
Functions of the nervous system.
What is send messages throughout the body, enabling communication and control of various bodily functions? (sensory input, integration/response, motor output)
Discrete structure with at least two different tissue types
What is an organ?
Brain, sensory receptors, nerves, spinal cord
What is nervous?
This mechanism helps counteract a stimulus to return back to balanced point.
What is a negative feedback?
Reproductive cycle of viruses where they integrate their DNA into the host cell.
What is lysogenic cycle?
Difference between somatic vs autonomic nervous system.
What is autonomic controls involuntary movements while somatic has voluntary control?
Smallest unit of all living things
What is an atom?
Thyroid gland, pituitary gland, pineal gland, thymus, adrenal gland, pancreas, ovary, testis.
What is endocrine?
If a butcher slices his finger and his finger starts to bleed, this feedback mechanism would kick in.
What is positive feedback?
