Anatomical Directions/ Everything Else Lab Flashcards
Gallbladder
small hallow organ on the posterior (inferior on humans) right side of the liver that stores bile
Proximal
nearer to the torso; used to describe limbs
Rectum
last part of the large intestine; stores feces before it is expelled from the anus
Spiral Colon
the wound up ascending colon; the ascending colon does not spiral in humans
Frontal Plane
divides the body into dorsal and ventral segments
Large Intestine
AKA colon; last part of the gastrointestinal tract; major site of water absorption
Cecum
first part of the large intestine, connected to the ileum; pouch that contains bacteria that breaks down plant material; in humans, the appendix is a bacterial reservoir attached to the cecum
Ileum
third and final section of the small intestine; absorbs nutrients
Jejunum
second section of the small intestine; absorbs nutrients
Dorsal
toward the back
Sagittal Plane
divides the body into left and right segments; midsagittal plane divides the body into left and right halves
Transverse Plane
divides a quadruped into anterior and posterior segments, but divides humans into superior and inferior segments
Deep
closer to the inside
Umbilical Cord
connection between the fetus and the placenta
Soft Palate
soft tissue covering the posterior roof of the mouth; closes off the nasal cavity during swallowing
Tongue
muscular organ in the mouth that aids with chewing and swallowing; important for speech in humans
External Nares
two outer openings of the nose
Hard Palate
thin bony plate that covers the roof of the mouth
Sublingual Glands
saliva producing tissue ventral and lateral to the anterior half of the tongue; smallest salivary glands
Toes
digits of the foot
Tail
flexible posterior appendage of the torso
Abdomen
region of the torso posterior (but inferior on humans) to the thorax; contains most of the digestive system
