AVS 1113 Midterm Basic Anatomy Flashcards
Cranial
Towards the head
Caudal
Toward the rear end
Ventral
Relates to the underside of an animal (Chest and abdomen)
Sternal
The Sternum
What can be used interchangeably
Sternal and ventral
Dorsal
Relates to the back of an animal
Medial
Towards the Midline
Midline
A medial line, especially the medial line or plane of the body divides the body into equal half
Lateral
Toward the side (away from the midline)
Recumbency
Lying down
Proximal
Towards the torso
Distal
Away from the torso
What is Juglar vein
Neck
What is the Cephalic Vein
Thoracic (front) Limbs
What is Saphenous
Pelvic (back) Limbs
What’s the difference between Thoracic vs pelvic limb
Thoracic is the front legs
Pelvic is the back legs
Skeletal System (Axial Vs Appendicular)
Axial
Bones found on the midline or attached to it (ribs skull vertebral column and sternum)
Appendicular
Bones of the limbs (humerus femur)
What does this system Include
All bones and joints of the body
What is the function
-Support soft tissues of the body
-Protect vital organs (Heart)
- act as levers for muscle attachment
-store minerals
-produce blood cells
Muscular System - Skeletal, Smooth, Cardiac
Skeletal
voluntary (attached to bones to cause movement), ie biceps triceps hamstrings
- Function is it produces movement of entire body or parts
Smooth
involuntary, ie arteries veins GIT reproductive system bladder
- Function is it maintains posture
Cardiac
Involuntary, heart muscles
Function is it produces heat
What does the Cardiovascular system include
Heart and blood vessels
What is an Artery
Carry blood away from the heart
Function: heart pumps blood to all parts of the body
What are veins
carry blood back to the heart, Deoxygenated
Function: heart made of 4 chambers right atrium, left atrium, right ventricle, left ventricle
Nostrils
external opening for air to enter/exit
Nasal cavity
warms, moistens, filters air
Larynx
passageway, vocal folds, covers trachea when swallowing
Trachea
passageway, connects larynx to lungs
Lungs
gas exchange
Mouth
chewing (mastication)
Esophagus
moves food from mouth to stomach
Stomach
mixes food with digestive enzymes
Small intestines
digestion, absorption
Large intestines
absorbs water
Rectum/Anus
exit route for eliminations
Ingestion (mouth)
taking in food, swallowing
Digestion (stomach)
breaking down food via mechanical and digestive enzymes
Peristalsis (intestines)
series of involuntary muscle contractions that move food
Absorption (intestines)
absorption of nutrients, minerals, and water
Defecation (rectum/large intestines)
pooping
Herbivore
plats ex rabbit, cattle, horse, sheep, goat
Carnivore
meat ex cat tiger +/- dog
Omnivore
plant and meat-eating animal ex rats pigs humans dogs
Integument system ( What does it include)
-skin
-coat/hair
-horns, claws, hooves, nails
Integument system (What is its fuctions)
-protective barrier
-site for vitamin d synthesis -sense organ: touch pain temperature, itch, physical and chemical stimuli - contains many glands and nerve receptors: sweat glands, heat receptor, pressure receptor, melanocytes
Urinary system (What does it Include)
-kidney
-Ureters
-Bladder
- Urethra
What is the function of kidney
Filters blood and removes wastes
Function of Ureters
Transports urine to bladder
Function of Bladder
Collects/stores urine
Urethra
transport urine from bladder for excretion (and semen in males)
Compare and contrast the different repro. organs and its functions between male and female
Males
Testicles: produces sperm, vas deferens (ductus deferens): connects testicles to urethra, accessory sex glands (prostate): produce semen (transport medium), penis: houses urethra organ used for copulation
Female
Ovaries: produces hormones and ovum (egg), uterus: houses and nourishes embryo/fetus, vagina: birth canal, vulva: external genital organ
What is CNS
Brain and spinal cord, function: controls most
Functions of the body and mind
What is PNS
contains of all nerves (outside of brain/spinal cord)
Function: connects CNS to organs skin limbs, carries sensory and motor information to and from CNS
