THEORY OF
PHYLEMBRYOGENESIS
This theory was put by Russian palaentologist Severtsov, postulating the
phylogenetic changes inn organisms are conditioned by ontogenetic
alterations, in that certain events are added or deleted in development
of embryo based on events of ancestral development.

3.

THEORY OF
PHYLEMBRYOGENESISANABOLISM
The process involving a sequence of chemical reactions that constructs or
synthsis molecules fronm smaller units using (ATP) in the process

4.

WHAT IS ANABOLISM

5.

FUNCTION OF ANABOLISM
Anabolic processes build organs and tissues. These
processes produce growth and differentiation of cells
and increase in body size, a process that involves
synthesis of complex molecules.

There is still much ongoing differential (DNA sequence based)
comparison research that is trying to separate out the simplest
forms of chordates. As some lineages of the 90% of species that
lack a backbone or notochord might have lost these structures
over time, this complicates the classification of chordates. Some
chordate lineages may only be found by DNA analysis, when there
is no physical trace of any chordate-like structures

Similarities in Chordata
Reproduction
Reproduction among members of this phylum is sexual, meaning that an
egg is fertilized by a sperm. There are a few animals in this group that
reproduce asexually, ''a'' meaning ''without sex.''

9.

Most chordates are dioecious, meaning that the males
and females of species are different (''di'' for ''two'').
For example, humans and other mammals, most fish,
birds, and reptiles, etc., have males and females that
have distinctly different reproductive organs. But
some chordates are hermaphroditic, meaning that
they have both male and female reproductive
structures.

Differences in Sexual
Reproduction
Since most chordates reproduce sexually, we're now going to switch to
talking about the differences in how this is accomplished. We know that
through this type of reproduction an egg is fertilized by a sperm, but
there are different ways that this can occur, as well as different paths
that the egg may take after fertilization
.

11.

There are two ways that eggs themselves
are fertilized. Most terrestrial species
will employ internal fertilization, where
the egg is fertilized inside the body,
while most aquatic species will employ
external fertilization

DEVELOPMENTAL
DISORDES OF HUMAN
REPRODUCTIVE SYSTEM
Reproductive system disease, any of the diseases and disorders
that affect the human reproductive system. They include
abnormal hormone production by the ovaries or the testes or by
other endocrine glands, such as the pituitary, thyroid, or
adrenals. Such diseases can also be caused by genetic or
congenital abnormalities, infections, tumours, or disorders of
unknown cause.

15.

16.

The main divisions of this article are concerned with (1) genetic
and congenital abnormalities, (2) functional genital disorders, (3)
infections, (4) structural changes of unknown cause, and (5)
tumours. For discussion of diseases and disorders affecting
pregnancy, see pregnancy. For diseases and disorders affecting
childbirth, see parturition.

Delayed puberty
The term delayed puberty may be a misnomer, because puberty delayed beyond
age 19 is in fact a permanent failure of sexual development because of an
abnormally low secretion by the pituitary gland of gonadotropic hormone, the
hormone that stimulates growth and activity of the sex glands; this condition is
called hypogonadotropic eunuchoidism. The term delayed puberty is usually
applied to boys who develop more slowly than the average but who still
eventually undergo full sexual development.
