What does trigeminal nerves innervate?
The trigeminal nerve, the fifth cranial nerve, innervates the face, providing sensation to the skin, mucous membranes, and sinuses. It has three major branches: the ophthalmic, maxillary, and mandibular nerves, which respectively supply the forehead, upper jaw, and lower jaw areas. Additionally, the mandibular branch also innervates muscles involved in mastication. Overall, the trigeminal nerve plays a crucial role in both sensory perception and motor functions of the face.
What are the three kinds of nervers?
The three kinds of nerves are sensory nerves, motor nerves, and mixed nerves. Sensory nerves transmit signals from sensory receptors to the central nervous system, allowing us to perceive stimuli. Motor nerves carry signals from the central nervous system to muscles, facilitating movement. Mixed nerves contain both sensory and motor fibers, enabling communication in both directions.
Nervous system major organs?
The major organs of the nervous system include the brain, spinal cord, and peripheral nerves. The brain controls cognitive functions, sensory perception, and voluntary movements. The spinal cord serves as a pathway for transmitting information between the brain and the rest of the body, while peripheral nerves extend from the spinal cord to innervate various organs and tissues throughout the body.
How many nerves are in each ear?
Each ear has three main nerves: the vestibulocochlear nerve, the facial nerve, and the vestibular nerve. These nerves are responsible for hearing, balance, and facial movement.
How many nerves in human hand?

Ne the different sections of the nerves?
The three main parts of the nerves includes the central nervous system, the peripheral nervous system and the autonomic nervous system.
What are the main three nerves?
i think you mean nervous systems; central (CNS), autonomic (ANS), and the sympathetic or para-sympathetic (SNS).
What are three things in the nervous system?
The nervous system is broken into the central and autonomic nervous systems. The central nervous system consists of the brain and spinal cord. The autonomic nervous system contains the peripheral nerves.
3 types of nerves in spinal cord?
The three types of nerves in the spinal cord are: afferent, efferent, and interneurons.

Motor nerves carry signals from the central nervous system to muscles, facilitating movement. Mixed nerves contain both sensory and motor fibers, enabling communication in both directions.
What are the three groups of nerves?
motor, sensory, mixed
What are three main parst of the nervous system?
The human nervous system can be divided into three main parts:Central nervous system (CNS) *is composed of brain and spinal cord...*Peripheral nervous system (PNS)*is composed of all body nerves that lie outside of your central nervous system...*Autonomic nervous system (ANS) *controls the involuntary actions of your body organs...*Central nervous system: brain, spinal cord, and association neuron. Not know where they belong by me: ganglia, cranial nerves, potential difference, excitability, somatic motor nervous system, autonomic nervous system. Peripheral nervous system (I think) has sympathetic division, and parasympathetic division.

How thick is a neuron?
Nerves vary in size. Nerves like the sciatic nerve are large while other are small. There are three types of nerves in the human body. Afferent, efferent, and mixed.
What three muscles are innervated by nerves?
Three muscles that are innervated by specific nerves include the biceps brachii, which is innervated by the musculocutaneous nerve; the quadriceps femoris, innervated by the femoral nerve; and the diaphragm, which is innervated by the phrenic nerve. Each of these nerves plays a crucial role in controlling muscle movement and function.
