CHAPTER 6- ANATOMY & PHYSIOLOGY Flashcards
Anatomy
Study of shape and structure of the human body
Physiology
Study of HOW the body functions
Anatomical position
Position of the body standing straight with face forward and palms resting
Posterior
Back
Anterior
Forward
Midsagittal plane (median or midline plane)
Vertical line that divides the body into equal left and right halves
Horizontal plane (transverse plane)
Divides the body into superior (upper) and inferior (lower) halves
Dorsal
On the back (facing the sky)
Ventral
On the front (facing the ground)
4 steps of how the human body is formed
CTOB
1.cells
2.tissues
3.organs
5.Body systems
What are cells
basic units of structure of the human body.
What are stem cells
Immature, specialized cells in the body. They can be induced to become other types of cells.
Nucleus
Control center of the cell
What does the nucleus contain
It contains a complete set of the body’s chromosomes which include the DNA
The four main tissues
ECMN
1.Epitelial
2.connective
3.muscle
4.nerve
What are body cavities?
a hole-> unoccupied space in the body
The two main cavities
1.Dorsal (located at the back oft he body)
2.Ventral Cavity (located at the front of the body)
The body is divided into how many regions?
2
What are the 2 body regions called? and where are they located?
1.Axial division : Head, neck, trunk
2.Appendicular division: arms & legs
