Neural activity is controlled by___

It releases growth hormones, which affect overall body development, especially height.

Main systems:

specializing in language

aids in the formation of the amniotic sac, placenta, and umbilical cord.

How does brain development peaks

responsible for producing various hormones

Contribute to sexual drive, bone, and muscle development.

shaped by both genetic factors and environmental influences.

One of the most well-known examples of genetic inheritance is the___

Hormones of male and female name

coordinates responses to both internal and external stimuli.

Nervous system parts:

___ aids in brain growth.

governs the functioning of other body systems.

___which either stimulate or inhibit neuron responses.

During a woman’s menstrual cycle, a mature egg is released from one of the ovaries each month and moves into the____ in a process called ___

What does thyroid gland produce

Key glands:

serves as a protective membrane for the developing cells.

spatial and creative tasks.

typically lasts about 40 weeks or 280 days, which includes an additional two weeks to account for ovulation and the last menstrual period

it regulates other glands.

These are the sex glands

Infants born after 42 weeks

Within 3-4 days after fertilization, the zygote moves along the fallopian tube and implants itself in the uterine wall.

__can occur if a sperm penetrates the egg.

traits that do become observable are part of the individual’s___

Embryo development:

This stage is particularly vulnerable, with the risk of spontaneous abortions or miscarriages being highest.

During this time, the organs continue to develop, and the fetus’s senses, like hearing and smell, become functional.

These hormones become more prominent during adolescence.

influences behavior based on the brain's development, which is the central organ of this system.

When does brain development peaks

contain genes responsible for the child's characteristics, such as physical traits (hair color, height, eye color), cognitive abilities (intelligence), personality tendencies, and susceptibility to certain hereditary diseases.

This system consists of glands throughout the body that release hormones directly into the bloodstream.

Through___ the zygote develops into a blastocyst, which not only serves a protective role but also aids in the formation of the amniotic sac, placenta, and umbilical cord.

By the end of the 8th week, limb buds resembling underdeveloped limbs appear.

testes in males and ovaries in females

This zygote, while traveling to the ___, forms a ___

The union of the sperm and egg is called___ Resulting in a__

This signals that the woman is ready for pregnancy, as fertilization can occur if a sperm penetrates the egg.

Info As people age, brain cells decline, impacting cognitive functions like memory, motor skills, and sensory processing.

This is the longest stage of prenatal development, lasting from the 8th week until birth.

governs higher mental processes.

Central Nervous System (CNS) parts:

What does a zygote inherit from each parent

The development of the ___ around neurons enables faster signal transmission, which is why reflexes dominate newborn behavior before voluntary actions take over.

ranges from 37 to 41 weeks.

Infants born before 37 weeks

Through mitosis (cell division), the zygote develops into a blastocyst, which not only serves a protective role but also aids in the formation of the amniotic sac, placenta, and umbilical cord.

How old does brain lateralization occurs,

the major organs and biological systems (respiratory, digestive, nervous) begin to form.

Stages of Prenatal Development:

A deficiency in this hormone may lead to mental impairments or learning difficulties.

Chromosome of male

Chromosome of female

The mother can feel the fetus's movements, and the fetus may start responding to external stimuli, such as the mother’s heartbeat and voice.

produce reproductive hormones.

___transmits signals between the CNS and the rest of the body.
