Anatomical planes are what?

imaginary slices through animal bodies

- used as reference points to describe positions or to indicate how a part of the body is being viewed

What are the approaches to the study of Anatomy and Physiology?

Microscopic anatomy - deals with structures so small we need a microscope to see them clearly
Macroscopic anatomy - also called gross anatomy - deals with body parts large enough to be seen with the unaided eye, such as organs, muscles, and bones
Regional anatomy (individual  regions) vs. systematic anatomy (individual systems)

What is carpus?

the proximal-distal dividing line for the front leg

What is tarsus?

the dividing line for the rear leg

What is bilateral symmetry?

means that the left and right halves of an animal's body are mirror images of each other. the principle of bilateral symmetry accurately reflects the basic inner and outer structure of the body. (paired structures such as the kidney's, lungs, and legs - approx mirror images)

What are the body cavities?

a small dorsal cavity and a much larger ventral cavity

What is the dorsal body cavity?

contains the brain and spinal cord, this is the central nervous system.

What is the ventral body cavity?

much larger than the dorsal one. it contains most of the soft organs (viscera) of the body. It is divided by the thin diaphragm muscle into the cranial thoracic cavity - also known as thorax or chest, caudal abdominal cavity - abdomen

What is the pleura?

a thin membrane that covers the organs in the thoracic cavity - even the cavity itself is lined by pleura

What is the layer that covers the organs?

visceral layer of pleura

What is the layer that lines the whole thoracic cavity?

parietal layer of pleura

Cranial surface means?

The "front" surface of the leg

Caudal surface means?

The "back" surface of the leg

Dorsal surface means

The area that is distal to the carpus and tarsus, the area that includes the "front" of the leg and the top of the foot

Palmer surface is ...?

The area on the "back of the limb, including the bottom of the foot on the front leg

Plantar surface is ...

The area on the "back of the limb, including the bottom of the foot on the hind leg

A dorsal recumbent animal is lying on its...?

back (dorsal surface) with its belly facing upward

An animal in sternal recumbency is....?

the opposite of dorsal recumbency. It is lying on its sternum (ventral surface) with its back facing upward

Lateral recumbency describes an animal lying...?

on its side. Add left and right indicates which side the animal is lying on

An animal lying on its right side is in ...?

right lateral recumbency

An animal lying on its left isde is in ...?

left lateral recumbency

An animal positioned with their bodies tilted between true dorsal or sternal and true lateral recumbency is known as ?

oblique recumbency

The mouth, intestines, and urinary bladder are lined with ______ tissue.

epithelial

_____ are made up of groups of tissues that work together for common purposes.

organs

_______ muscles moves the bones of the skeleton and is under conscious nervous system control.

skeletal

True or False. The nervous system is composed of glands and hormones?

False

True or False. Systems are the most complex level of body organization?

True - systems are groups of organs that are involved in a common set of activities.

The ventral body cavity is much larger than the dorsal one, it contains ...?

most of the soft organs (visera) of the body It is divided by the thin diaphragm muscle into the cranial thoracic cavity, or thorax or chest & the caudal abdominal cavity, known as the spinal cord. It is formed by the vertebrae of the spine, and it houses and protects the spinal cord
