Mitosis
What is mitosis?
The division of a cell into two identical daughter cells
What is meiosis?
The process which a cell divides two times forming four daughter cells with half of the genetic information.
What does "automatic" means in the human body?
it is responsible for many functions that you don’t have to think about to control.
Different and many tissues together form an...
organ
The muscles of the human body that work the skeletal system, that are under voluntary control are responsable for: (3)
movement, posture, and balance.
In which part of the mitosis process does the cells starts to get ready for it.
Interphase
What is a chromosome?
A DNA molecule with all our genetic material.
It relaxes your body after periods of stress or danger. It also helps run life-sustaining processes, like digestion, during times when you feel safe and relaxed.
Parasympathetic Nervous System (PSNS)
Describe how does your nervous system send signals to other parts of the body
With neurons. They create a web of terminals that sends the signals through the nerves.
Name the three types of muscles that the human body has
Striated (or skeletal), smooth and cardiac
In which step does the cell starts to separate the chromosomes to each extreme side of the cell.
What is a chromatid?
A copy of a chromosome with half of the genetic material.
It is activated with the "fight or flight" response. It increase when you are stressed or in danger.
Sympathetic Nervous System (SNS)
Give three examples of a human body system
nervous, muscular, skeletal, reproductive, endocrine, digestive, tegumentary, etc
Your shoulder muscles, hamstring muscles and abdominal muscles are all examples of..
Striated (or skeletal)
Describe what happends during metaphase
Chromosomes line up in the center of the cell to prepare to separate.
How many organisms are involved in meiosis?
Two. As it is sexual reproduction and it needs gamets. (Sperm and egg cells)
Give three examples of what your parasympathetic nervous system do.
Digestion, slow heart rate, slow breathing, sleep.
Explain at least three things your nervous system do
Thoughts, memories, feelings, movement, senses, healing, sleep, digestion, etc.
This attach skeletal muscle tissue to bones throughout your body.
Tendons
In class, we learned about a hand game to remember each phase. Demonstrate each one.
Interphase
Prophase
Anaphase
Metaphase
Telophase
Cytoquinesis
Describe the process of meiosis.
Interphase, prophase, metaphase, anaphase, telophase and cytoquinesis. Then from those two cells they repeat again. Interphase 2, prophase 2, metaphase 2, anapahse 2, telophase 2 and cytoquinesis 2.
Explain how does your senses work. (Only 1)
First we sense a stimuli with our receptors (light in the eyes).
Then an impulse in send to the brain for it to make a desicion or trasmit a sense.
The impulse is sent by neurons and nerves to create an effector.
Name the three parts of the nervous system
Brain, spinal cord and nerves.
Describe what are smooth muscles.
They are involuntary muscles that your autonomic nervous system controls. The tissue found in the walls of hollow organs, such as the intestines, uterus and stomach. Also skin and eyes.
