The main functions of the epithalamus is to secrete melatonin and regulate emotions. It also regulates the motor pathways of the human body.
diencephalon
Thalamus, epithalamus, hypothalamus....
to connect the habenular nuclei of the two sides of the epithalamus together.
It's also known as epithalamic commissure.
to connect the habenular nuclei of the two sides of the epithalamus together.
The diencephalon consists of thalamus, hypothalamus, and epithalamus.
There are two structures that make up the Diencephalon. The main structure of the diencephalon is hypothalamus thalamus and the second is the subthalamus.
It is formed of transverse decussating fibres of both sides that are derived from posterior commsiural nucleus, interstitial nucleus of Cajal and Darkschewitsch nucleus.
its main function is to house the pineal gland (part of the endocrine system), which secretes melatonin. it also contains the choroid plexus of the third ventricle in the brain which forms cerebral spinal fluid.
They are organised into categories. Those categories are: Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions External functions Cube functions
There are infinitely many types of functions. For example: Discrete function, Continuous functions, Differentiable functions, Monotonic functions, Odd functions, Even functions, Invertible functions. Another way of classifying them gives: Logarithmic functions, Inverse functions, Algebraic functions, Trigonometric functions, Exponential functions, Hyperbolic functions.
You could not really classify formulas into types as the amount of formulas are infinite and you can have a variety of things happening in a formula. Functions come in categories, and that is maybe what you mean. It will depend on which version of Excel you have, but these are the categories available in later versions: Cube functions Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions
