Nervous System Anatomy

The nervous system detects environmental changes that impact the body then works in tandem with the endocrine system to respond to such events. The central nervous system the brain and spinal cord and the peripheral nervous system the nerves that carry impulses to and from the central nervous system.

Cerebrospinal fluid provides several vital functions to the central nervous system.

Nervous system anatomy. The ans has two arms. As with other higher vertebrates the human nervous system has two main parts. Csf absorbs shocks between the brain and skull and between the spinal cord and vertebrae.

The central nervous system and peripheral nervous system. Csf helps to maintain. It is composed of a specialized group of neurons that regulate cardiac muscle smooth muscles.

At every moment signals flood from the visceral organs into the cns. Movement of nerve impulses the movement of impulses through the nerve cell involving both chemical and biological changes. The nervous system consists of two subsystems.

The somatic involves parts of the body a person can command at will and the autonomic helps run involuntary functions such as pumping blood. The brain and spinal cord float within the csf reducing their apparent weight through buoyancy. The nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.

An encapsulated neural structure consisting of a collection of cell bodies or neurons in peripheral nervous system control specific body function multi polar neuron many dendrites one axon most common. Some cranial nerves that are also responsible for eye muscle control. Information conveyed through the nervous system moves along networks of cells called neurons.

These neurons can only send information one way. The skull and three meninges the dura mater arachnoid mater and pia mater protect the brain. Autonomic nervous system composition.

The medulla oblongata is the lowest part of the brainstem and is interconnected with the cervical. For example skeletal muscle contracts to move the skeleton cardiac muscle is influenced as heart rate increases during exercise and smooth muscle contracts as the digestive system moves food along the digestive tract. The pons serves as a bridge between the midbrain and the medulla oblongata.

The sympathetic division and the. Human nervous system system that conducts stimuli from sensory receptors to the brain and spinal cord and conducts impulses back to other parts of the body. Nervous system organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs.

Tissues of the pns and cns are formed of cells called glial cells and neurons. The midbrain is located below the hypothalamus. The nervous system can cause the contraction of all three types of muscle tissue.
