| The hard palate consists of portions of: | four bones: two maxillae and two palatines. |
| The right angle between the transverse colon and the ascending colon is the: | hepatic flexure |
| The proper anatomical order for the divisions of the colon is: | ascending, transverse, descending, and sigmoid. |
| anatomy | The study of the structures of the body |
| calcium ions | Serves as the actual "trigger" for muscle contraction by removing the inhibition of the troponin molecules |
| midsagittal plane | Plane that divides the body into a right and left side |
| anatomical position | Body facing forward, feet are parallel to each other, arms are at he sides with the palms facing forward |
| ventral cavity | Anterior surface of torso; divided by diaphragm muscle into upper thoracic cavity and abdominopelvic cavity |
| dorsal cavity | back part of the body; two subdivisions are cranial and spinal |
| reflex arc | sensory receptor, sensory neuron, motor neuron, and effector that are involved in a quick response to a stimulus |
| The portions of the central nervous system that are abundant in axons rather than cell bodies of neurons. The color derives from the presence of the axon's myelin sheaths | white matter |
| gray matter | Brain and spinal cord tissue that appears gray with the naked eye; consists mainly of neuronal cell bodies (nuclei) and lacks myelinated axons. |
| Central nervous system | Consists of the brain and spinal cord |
| a flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone. | tendons |
| ligament | A strong band of connective tissue that connects bones to one another. |
| Bone forming cell | osteoblasts |
| Bone-dissolving cells. they break down bone and release its minerals to the blood. | osteoclasts |
| pathway of light into the eye | cornea--aqueous humor--lens--vitreous humor--retina |
| appendicular skeleton | Bones of the limbs and limb girdles that are attached to the axial skeleton |
| Portion of the skeletal system that consists of the skull, rib cage, and vertebral column | axial skeleton |
| sympathetic nervous system | A subdivision of the autonomic nervous system that activates nerves, glands and visceral muscles in times of stress or threat (prepares the body for action) |
| Chemical messengers, mostly those manufactured by the endocrine glands, that are produced in one tissue and affect another | hormones |
| An antigen-binding immunoglobulin, produced by B cells, that functions as the effector in an immune response. | antibodies |
