is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.

system is mostly located outside of the body.

male reproductive system EXTERNAL

male reproductive system INTERNAL

is responsible for sexual function, as well as urination.

is the surgical removal of foreskin from a baby's penis

systems consists of internal and external organs

It creates hormones and is responsible for fertility, menstruation and sexual activity.

is the process of formation of female gametes

female gamete is known as an

It is the type of gametogenesis through which ova or the female gametes are formed, and this female gamete is known as an ovum.

These hormones play an important role in female traits, such as breast development, body shape, and body hair.

They are also involved in the menstrual cycle, fertility, and pregnancy.

One of a pair of female glands in which the eggs form and the female hormones estrogen and progesterone are made.

Once the egg has left the ovary it can be fertilized and implant itself in the lining of the

is to nourish the developing fetus prior to birth.

These glands are believed to secrete a substance to lubricate the urethra opening.

This substance is also believed to act as an antimicrobial.

are located on each side of the vaginal opening.

These glands secrete fluid that helps lubricate the vagina.

this is the pleasure center of female's reproductive anatomy

Many people think of the ____ as the tiny nub of flesh located at the top of the genitals (vulva), but this is just the part of the ___ you can see.

4 phases of menstrual flow

also known as period

is when blood and tissue from your uterus comes out of your vagina.

it usually happens once every month

refers to that part of your menstrual cycle when an egg matures in your ovaries.

During this time, the level of the hormone estrogen rises, which causes the lining of your uterus (the endometrium) to grow and thicken.

During days 10 to 14,.none of the developing follicles will form a fully mature egg (ovum).

is the process in which a mature egg is released from the ovary.

After it's released, the egg moves down the fallopian tube and stays there for 12 to 24 hours, where it can be fertilized.

prepares your uterus for pregnancy by thickening your uterine lining.

A disorder involving your ______ can affect getting and staying pregnant.

how do we take care of our reproductive system

occurs when a sperm fertilizes an egg (fertilization) after it’s released from the ovary during ovulation.

The fertilized egg then travels down into the uterus, where ____ occurs. A successful ____ results in pregnancy.

is a network of neurons whose main feature is to generate, modulate and transmit information between all the different parts of the human body.

This property enables many important functions of the ______, such as regulation of vital body functions (heartbeat, breathing, digestion), sensation and body movements.

vital body functions

preside over everything that makes us human; our consciousness, cognition, behaviour and memories.

This is the basic unit structure and function of the nervous system.

parts of the neuron

are branched cell components that receive stimulus from the other neurons or sensory receptors.

contains a nucleus, which will process the stimulus.

will transmit stimulus to a gland, muscle, organ or other neuron.

central nervous system

intergrate and control centers

peripheral nervous system

somatic and visceral sensory nerve fibers

conducts impulses from the receptors to the CNS.

conducts impulses from the CNS to effectors (muscle and glands)

somatic motor (voluntary)

conducts impulses from the CNS to skeletal muscles

visceral motor (involuntary)

conducts impulses from the CNS to cardiac muscle, smooth muscles and glands

Autonomic NS

mobilizes body systems during activity

FIGHT or FLIGHT system

conserve energy

Rest and Digest System

carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord)

carry motor information away from the central nervous system to the muscles and glands of the body.

negative feedback

This is a control system to “reduce or minimize” any changes or conditions of the body, which help the whole body system to be stable.

a process that detects and reverses deviations from normal body constants

negative feedback loop 3 parts:

found throughout every body organ and tissue

function is to send nerve impulses (stimuli) to the brain in response to environmental information.

monitor the body's internal condition, such as temperature, blood ph, blood sugar, and blood pressure, on a continual basis

A molecule inside or on the surface of a cell that binds to a specific substance and causes a specific effect in the cell.

is a controlling point or the supervisor, which gathers all the information from different organs.

best examples of integrators

The brain functions in interpreting the messages from the nervous system.

is a part of the body which can respond to a stimulus according to the instructions sent from the nervous system (spinal cord and brain).

examples of effector

This is a control system that uses information from sensors to “increase” the rate of processes.

Example: During labor, the oxytocin release in the uterus intensifies and speeds up contractions.

The release of oxytocin stops when the baby is born.

The birth ends the release of oxytocin and ends positive feedback.

is a complex network of glands and organs

It uses hormones to control and coordinate your body's metabolism, energy level, reproduction, growth and development, and response to injury, stress, and mood.

happy hormones

the reward chemical

is most notably involved in helping us feel pleasure as part of the brain's reward system.

love hormone

is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary.

plays a role in social bonding, reproduction, childbirth, and the period after childbirth.

the painkiller

are chemicals (hormones) your body releases when it feels pain or stress.

They're released during pleasurable activities such as exercise, massage, eating and sex too.

help relieve pain, reduce stress and improve your sense of well-being.

the mood stabilizer

is a neurotransmitter that mediated satisfaction, happiness and optimism.

are reduced in depression, and most modern anti-depressant drugs, known as Serotonin Reuptake Inhibitors (SSRIs), act by increasing the amount of serotonin available to brain cells.

SSRIs

is any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival.
