Nervous System
The portion of the vertebrate central nervous system enclosed in the skull and continuous with the spinal cord through the foramen magnum that is composed of neurons and supporting and nutritive structures (such as glia) and that integrates sensory information from inside and outside the body in controlling autonomic function (such as heartbeat and respiration), in coordinating and directing correlated motor responses, and in the process of learning.
What is the brain?
The axial skeleton of a vertebrate that consists of an articulated series of vertebrae which extend from the neck to the tail and protect the spinal cord.
What is the backbone/spine?
The fringe of hair edging the eyelid.
What is the eyelash?
The part of a tooth external to the gum or an artificial substitute for this.
What is the crown?
The space that is formed when the two layers of the pleura spread apart.
What is the pleural cavity?
The cord of nervous tissue that extends from the brain lengthwise along the back in the spinal canal, gives off the pairs of spinal nerves, carries impulses to and from the brain, and serves as a center for initiating and coordinating many reflex acts.
What is the spinal cord?
A bone of the shoulder girdle typically serving to link the scapula and sternum.
What is the collarbone/clavicle?
Either of the movable folds of skin and muscle that can be closed over the eyeball.
What is the eyelid?
A hard calcareous substance that forms a thin layer capping the teeth.
What is the enamel?
The natural opening through which food passes into the body of an animal and which in vertebrates is typically bounded externally by the lips and internally by the pharynx and encloses the tongue, gums, and teeth.
What is the mouth?
Any of the filamentous bands of nervous tissue that connect parts of the nervous system with the other organs, conduct nerve impulses, and are made up of axons and dendrites together with protective and supportive structures.
What are the nerves?
A basin-shaped structure in the skeleton of many vertebrates that is formed by the pelvic girdle and adjoining bones of the spine.
What is the pelvis?
The more or less globular capsule of the vertebrate eye formed by the sclera and cornea together with their contained structures.
What is the eyeball?
The soft sensitive tissue that fills the central cavity of a tooth.
What is the pulp?
A thin plate of flexible cartilage in front of the glottis that folds back over and protects the glottis during swallowing.
What is the epiglottis?
The part of the nervous system which in vertebrates consists of the brain and spinal cord, to which sensory impulses are transmitted and from which motor impulses pass out, and which coordinates the activity of the entire nervous system.
What is the central nervous system?
The inner and usually larger of the two bones of the vertebrate hind or lower limb between the knee and ankle.
What is the shinbone/tibia?
The transparent part of the coat of the eyeball that covers the iris and pupil and admits light to the interior.
What is the cornea?
A specialized bony layer of connective tissue covering the dentin of the part of a tooth normally within the gum.
What is the cementum?
The part inside your mouth where the passages of the nose connect to your mouth and throat.
What is the pharynx?
It is a small but important area in the center of the brain. Its main role is to keep the body in homeostasis as much as possible. It acts as the connector between the endocrine and nervous systems to achieve this.
What is the hypothalamus?
The proximal bone of the hind or lower limb that extends from the hip to the knee.
What is the thighbone/femur?
The opaque contractile diaphragm perforated by the pupil and forming the colored portion of the eye.
What is the iris?
Any of the vessels through which blood circulates in the body.
What is a blood vessel?
The left lung does not have it.
What is the middle lobe?
