the vertebral joint closer to the tail

The caudal articular process refers to the joint that is located closer to the tail in the vertebral column. This process is responsible for connecting adjacent vertebrae and facilitating movement and flexibility in the spine. It allows for the articulation and rotation of the vertebrae, contributing to the overall mobility of the tail region.

the articulation at this point

The term "lumbosacral joint" refers to the joint between the lumbar spine and the sacrum. This joint is located at the lower part of the spine, where the lumbar vertebrae meet the sacrum bone. It plays a crucial role in providing stability and allowing movement between the lower back and the pelvis. The lumbosacral joint is responsible for transferring the weight of the upper body to the pelvis and lower extremities, making it an important point of articulation in the body.

9. In the spinal cord the medulla is _________ matter.

The medulla in the spinal cord is composed of grey matter. Grey matter contains nerve cell bodies, dendrites, and unmyelinated axons. It is responsible for processing and transmitting information within the nervous system. In contrast, white matter consists of myelinated axons and is responsible for transmitting signals between different parts of the nervous system.

fluid filled inner space

The arachnoid space refers to the fluid-filled inner space between the arachnoid membrane and the pia mater, two of the three membranes that surround and protect the brain and spinal cord. This space contains cerebrospinal fluid, which acts as a cushion and helps to protect the central nervous system from injury. The arachnoid space also contains blood vessels that supply nutrients to the brain.

inner layer tightly wrapped around spinal cord

The pia mater is the innermost layer of the meninges, which are protective membranes that surround the brain and spinal cord. It is a thin and delicate layer that adheres closely to the surface of the spinal cord, providing a protective barrier. The pia mater contains blood vessels that supply nutrients to the spinal cord and helps to cushion and support it.

the crack (i guess) on the bottom side

The given answer, "ventral medial fissure," is likely the correct answer because it accurately describes the crack or fissure on the bottom side of an object. The term "ventral" refers to the underside or belly, and "medial fissure" suggests a central or middle crack. Therefore, this answer appropriately identifies the location and nature of the crack.

the space (white matter) on the top

The correct answer is "dorsal funiculus." The term "dorsal funiculus" refers to the space or region within the spinal cord that contains white matter. White matter is composed of myelinated nerve fibers and is responsible for transmitting signals between different areas of the spinal cord and the brain. The dorsal funiculus is located on the top or dorsal side of the spinal cord and is involved in carrying sensory information, such as touch, temperature, and proprioception, from the body to the brain.

17.

the space (white matter) on the sides

The correct answer is lateral funiculus. The lateral funiculus refers to the space or region of white matter located on the sides of the spinal cord. It contains ascending and descending nerve fibers that transmit sensory and motor information between the brain and the rest of the body. This region plays a crucial role in relaying information and coordinating movement and sensation.

the vertebral joint closer to the head

The cranial articular process refers to the joint located closer to the head in the vertebral column. This process is responsible for connecting the vertebrae and allowing movement and flexibility in the neck and head region. It is an important component of the vertebral joint and plays a crucial role in maintaining the stability and range of motion of the spine.
