What is the definition of anatomy?

The study of the structures of an organism and the relationship of the organism to its parts.

It is descriptive.

1

What is physiology?

Involves the study of the functioning of living organisms and their parts.

2

What is the definition of anatomical position?

It is a reference point used for descriptive purposes. The person is facing the observer, looking forward, and is erect. Palms and feet also forward and arms down to the side.

3

Biped

An animal that walks on two feet.

4

Quadruped

An animal that walks on four feet.

5

Anterior

Towards the front of the body or toward the nose in quadrupeds.

6

Posterior

Towards the back of the body or the tail in quadrupeds.

7

Ventral

Towards the belly and is synonymous in bipeds with the anterior position.

8

Dorsal

Towards the backbone, like posterior position.

9

Superficial

Towards the surface of the body.

10

Deep

Away from the surface of the body.

11

Superior

Above, upper

12

Inferior

Below or lower

13

Rostral

Towards the head (beak)

14

Caudal

Towards the tail (end of spinal cord)

15

External

Towards the outer surface of the body. Used to describe cavities and walls.

16

Internal

Towards the inner surface of the body. Describes body cavities and walls.

17

Medial

Towards the midline.

18

24

What is a neuron?

The basic structural and functional unit of the nervous system. It transmits messages and neural impulses throughout the nervous system.

25

What are dendrites?

Process of the cell that collects and receives info/impulses from other cells and transmits impulses toward the cell body by way of electrical disturbances.

Dendrites are typically short and highly branched.

26

What is 'chaos'?

Electrical energy or billions of impulses.

27

Dendritic spines

Highly branched dendrites which can absorb a greater amount of impulses and are not covered.

28

Which type of neurons are highly branched?

Motor neurons bc they need impulses to be not interrupted.

29

Axons

Typically long, thin processes that transmit impulses away from the cell body.
