AP PSYCHOLOGY

Detailed explanation-1: -The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1]. It is also responsible for the reflex arc, which involves the use of interneurons to perform reflexive actions. Besides these, there are thousands of other association nerves in the body.

Detailed explanation-2: -The sensory-somatic nervous system is made up of cranial and spinal nerves and contains both sensory and motor neurons. Sensory neurons transmit sensory information from the skin, skeletal muscle, and sensory organs to the CNS.

Detailed explanation-3: -1: Spinal nerves: Spinal nerves contain both sensory and motor axons. The cell bodies of sensory neurons are located in dorsal root ganglia.

Detailed explanation-4: -Neural pathways that connect the brain and the spinal cord are called the ascending and descending tracts. They are responsible for carrying sensory and motor messages to and from the periphery.

Detailed explanation-5: -The spinal cord is a vital aspect of the CNS found within the vertebral column. The purpose of the spinal cord is to send motor commands from the brain to the peripheral body as well as to relay sensory information from the sensory organs to the brain.
