When opening a sterile package, you should pick up the package w the tab or sealed edge pointing ________
Towards you
Location of Medulla Oblangata and what it is responsible for:
Located in the lowest part of the brain stem.
Responsible for regulating heartbeat and respiration.
Cerebellum location and responsibility
Located in the section below the back of the cerebrum.
Responsible for muscle coordination, balance, posture, muscle tone.
Meninges
Three membranes that cover and protect the brain and spinal cord.
Dura Mater- thick outer layer
Arachnoid membrane- delicate, weblike middle layer
Pia mater- innermost later that nourishes nerve tissue
Neuron
Basic structural unit of the nervous system
Cerebrospinal fluid functions
Carries nutrients to parts of the brain and spinal cord.
Removes metabolic products and wastes.
Shock absorber to protect brain and spinal cord
Parasympathetic nervous system
Slows heart rate, decreases respirations, lowers bp, stimulates the digestive tract
Sympathetic nervous system
Increase heart rate, respiration, and bp. Slows down activity in digestive tract.
Parasympathetic and sympathetic nervous system…
Work together to maintain homeostasis (a balanced state) to control involuntary body functions at proper rates
Somatic nervous system consists of…
12 pairs of cranial nerves
31 pairs of spinal nerves
Cranial nerves
Responsible for senses and sends out impulses for both involuntary and voluntary muscle control
Spinal nerves
Carries messages to and from spinal cord and include both sensory (afferent) and motor (efferent) nerves.
Leukocytes
White blood cells which fight infection
Erythrocytes
Red blood cells
Anemia
Inadequate number of red blood cells or low hemoglobin levels or both
Atrium (heart)
Upper chamber of heart
Myocardium (heart)
Muscular middle layer of heart
Ventricle (heart)
Lower chamber of heart
Pericardium (heart)
Double layered membrane on outside of heart
Septum (heart)
Muscular wall which separated the heart into a right and left side.
Systole definition and the process
A period of ventricular contraction (following diastole)
- atria contracts and pushes blood into ventricles
-atria relaxed and fills w blood
-right ventricle pushes blood into the pulmonary artery
-left ventricle pushes blood into the aorta
Parts in order of the conductive pathway for electric impulses in the heart
Sinoatrial node
Atrioventricular node
Bundle of his
Right and left bundle branches
Perkinje fibers
SABRP
Aorta (blood vessel)
Largest artery in body
Arteries (blood vessel)
Muscular and elastic blood vessels
Capillaries (blood vessel)
vessels that allow oxygen and nutrients to pass through to cells
Inferior and superior vena cava (blood vessel)
Largest veins in body
Veins (blood vessels)
Vessels that contain valves to prevent back flow of blood
Lacteals
Lymphatic capillaries that pick up digested fats or lipids
Cisterna Chyli
Pouch like structure at the start of the thoracic duct where purified lymph is stored
Thoracic duct
A larger tube that drains the lymph from the rest of the body and empties into the left subclavian vein
Adenitis
inflammation of the lymph nodes
Lymphangitis
Inflammation of the lymphatic vessels
Lymphatic capillaries
Small open-ended vessels that pick up lymph at tissues throughout the body
Lymph nodes
Produce lymphocytes and antibodies for the immune system
Functions of the spleen
Produced leukocytes and antibodies
Destroys erythrocytes (red blood cells)
Filters metabolites and wastes
Fallopian tubes purpose and location
Serves as passageways for a mature ovum to move from the ovary to the uterus.
An area for fertilization.
Attached to the upper part of the uterus.
One of the most common sexually transmitted diseases
Chlamydia
Epididymis
Stores sperm while they mature and become mobile.
Located in the scrotum and above the testis
Prostate gland
Contracts during ejaculation to empty the semen into the urethra.
A donut shaped gland located below the urinary bladder and in either side of the urethra.
Seminal gland
Produces thick yellow fluid that provides nourishment for the sperm
Testes
Produces sperm and the male hormone testosterone.
lol tater in the scrotum, a sac suspended between the thighs
Vas deferens
Passageway and temporary storage area for sperm.
Joins w the epididymis and extends up the abdominal cavity where it curves behind the urinary bladder and joins w a seminal vesicle
Cervix
Connects the uterus w the vagina
Lower narrow end I’d the uterus that forms a canal between uterus and vagina

Area for fertilization
Attached to the upper part of the uterus
Ovary
Produce the ovum and female hormones
Located in the pelvic cavity
